In this paper, how to analyses the downlink performance of the cellular system combining with site diversity operation and antenna diversity is introduced first. On the basis of Gaussian approximation of the interference components, the changes of bit error rate (BER) in the given set of channel is expressed in receiving signals. By using the Monte-Carlo numerical method, the local average BER is then calculated through comparing the conditional BER with the given set of channel gains. The outage probability is considered to measure the distribution of the local average BER and the downlink ca

Abstract:
Recently, filter bank multicarrier with offset quadrature amplitude modulation (FBMC/OQAM) has received increasing attention from researchers, owing to its merits and superior spectral efficiency. High peak-to-average power ratio (PAPR) occurs in approximately all multicarrier systems, including FBMC/OQAM, and may cause bit-error-rate (BER) degradation if not appropriately handled. Conventional PAPR reduction methods for orthogonal frequency division multiplexing (OFDM), such as partial transmit sequence (PTS), selective mapping (SLM), and discrete Fourier transform (DFT) spreading, are ineffe

The performance of the systerm BER is analysised, then PAPR is reduced by using the method through simulation.

Companding transform is a simple and efficient method in reducing the Peak to Average Power Ratio (PAPR) of Orthogonal Frequency Division Multiplexing (OFDM) systems. In this project, a novel nonlinear companding scheme is proposed to reduce the PAPR and improve Bit Error Rate (BER) for OFDM systems. This proposed scheme mainly focuses on compressing the large signals, while maintaining the average power constant by properly choosing transform parameters. Moreover, analysis shows that the proposed scheme without decompounding at the receiver can also offer a good BER performance. Finally, simu

As a result of the rapidly increasing mobility of sensor nodes, mobile wireless sensor networks (MWSNs) would be subject to multiple carrier frequency offsets (MCFOs), which result in time-varying channels and drastically degrade the network performance. To enhance the performance of such MWSNs, we propose a relay selection (RS) based double-differential (DD) cooperative transmission scheme, termed RSDDCT, in which the best relay sensor node is selected to forward the source sensor node’s signals to the destination sensor node with the detect-and-forward (DetF) protocol.

Orthogonal frequency division multiplexing (OFDM) has become a very popular method for high-data-rate communication. However, it is well known that OFDM is plagued by a large peak-to-average power ratio (PAPR) problem. This high PAPR results in overdesigned power amplifiers, which amongst other things leads to inefficient amplifier usage, which is undesirable. Various methods have been recommended to reduce the PAPR of an OFDM transmission; however, all these methods result in a number of drawbacks.

The results showed that the groynes appeared effective in keeping the main core of high streamwise velocity away from the outer bank wall in the region where they were installed, although high potential still existed for local scour around the groynes.

Full text
Abstract:
Business environment reform (BER) targets inadequate business regulations. It is intended to remove constraints to business investment, enabling growth and job creation, and create opportunities for international business to contribute to and benefit from this growth. However, there is a lack of detailed knowledge of the impact of BER on gender and inclusion (G&I). While a review of existing literature suggests that in general, there is no direct link between BER and G&I, indirect links are likely through the influence of BER on firm performance. Outcomes will be influenced by the diff

Abstract:
In 2006 Congaree National Park (CONG), in conjunction with the Southeast Coast Network (SECN) Inventory and Monitoring Program, began collecting water-quality data at Cedar Creek as part the NPS Vital Signs Monitoring Program. The continuous-monitoring data station is located approximately one mile south of the visitor center and collects water temperature, dissolved oxygen, pH, specific conductance, turbidity and water-level data every 30 minutes. This publication summarizes data collected from January 1, 2012 to December 31, 2012. The CONG fixed-station water-quality monitoring site is part

Abstract:
The objective of this study was to examine different methods available for estimating the average reservoir pressure of an underground storage reservoir and to determine the relative accuracy of each technique under varying conditions. Three techniques were reviewed, including a new procedure developed as a part of this research project. Approach 1: Shutting-in all wells and monitoring several wells or one representative well upstructure after a selected length of time. Either the arithmetic or weighted average of the final pressure for all the wells is used to determine the average reservoir

Abstract:
This study was conducted in response to Technical Assistance Request (TAR) 20133, which identified a need for a baseline acoustic inventory within a discontinuous parcel of Sleeping Bear Dunes National Lakeshore (SLBE). Although the Bow Lakes parcel is frequented by visitors seeking a quiet refuge away from crowds, it is bordered by three privately owned and operated sand and gravel mines. The park needs information about existing and natural ambient sound levels to evaluate the effects of mining noise on the parcel. In March-April 2022, the Natural Sounds and Night Skies Division (NSNSD) gath

Full text
Abstract:
Do all exporters benefit the same from export promotion programs? Surprisingly, not matter how obvious this question may a priori be when thinking of the effectiveness of these programs there is virtually no empirical evidence on how they affect export performance in different parts of the distribution of export outcomes. This paper aims at filling this gap in the literature. We assess the distributional impacts of trade promotion activities performing efficient semiparametric quantile treatment effect estimation on assistance, total sales, and highly disaggregated export data for the whole po

Abstract:
Understanding the available mineral resources in Great Salt Lake brine is an important component to managing these resources into the future. This study examined the in-place resource, or mass, of three economically important ions held within the brine: lithium, magnesium, and potassium. Interest in Great Salt Lake’s lithium has risen in recent years with society’s increased use of lithium in batteries, and magnesium and potassium have long been extracted from the lake. Using the Utah Geological Survey’s Great Salt Lake brine chemistry database, which contains data from 1966 to the present, th

Full text
Abstract:
The Yearly Average Method used in calculating State Contributory Pension entitlements has been criticised for creating anomalies, particularly for women. It has been announced that from 2034 onwards, entitlements will be based fully on the new Total Contributions Approach. This paper examines the impact of this move, examining who will gain or lose from this change. Overall, we find little change in the average weekly pension rate with a slight fall for men and no change for women. These average changes mask gains and losses for some; around 14 per cent of women and 12 per cent of men will fac
