Abstract:
An algorithm for iterative channel estimation using soft feedback for LTE uplink is proposed. The algorithm has low complexity compared to MMSE estimation and does not require knowledge of the channel statistics. A simple polynomial model is used for noise suppression across OFDM symbols and a DCT-based filter is used for noise suppression across subcarriers. The algorithm has been tested on several channel models and has been shown to provide a gain of about 0:5 dB with two estimation stages, compared to the no-feedback case. Further, the algorithm has been applied to a MIMO case. A compariso

Abstract:
Abstract Uplink resource allocation strategies in modern cellular networks are studied in this thesis. With the presence of multiple antenna transmission, multiple base station (BS) coordination and multicarrier techniques, the resource allocation problem is reformulated and jointly optimized over a large set of variables. The focus is on the sum power minimization with per user rate constraints. A centralized multicarrier coordinated cellular network with multiple antennas implemented at the BS side is considered, where BSs can be adaptively clustered to detect signals from one mobile station

In the past two decades, there has been a drastic increase in the mobile traffic, which is caused by the improved user experience with smart phones and its applications.

The work presented in this thesis focuses on designing new scheduling algorithms for uplink and downlink to effectively distribute resources among the users.

Rates of river channel change in three contrasting Scottish upland environments have been studied within the context of Climatic fluctuation and landuse changes over the last 250 years. The object of the research was to assess the spatial and temporal variation in channel types, the main controls on channel pattern and the dominant modes of channel adjustment. This was undertaken in a hierarchic framework with sites being investigated at three spatial scales. At a macro-scale, the spatial and temporal variation in channel pattern was evaluated through a random sample of river channel segments

Coarse sediment transfer in upland gravel-bed river systems is often neglected in the design and operation of river management schemes. Yet, it is increasingly attributed to problems within upland environments including bank erosion and enhanced flood risk.

Predicting future channel change and flood risk under varying management options requires numerical modelling.

Abstract:
Third generation partnership project (3GPP) long term evolution (LTE) uses single carrier frequency division multiple access (SC-FDMA) in uplink transmission and orthogonal frequency division multiple access (OFDMA) scheme for the downlink. A variable step size based least mean squares (LMS) algorithm is formulated for a single carrier frequency division multiple access (SC-FDMA) system, in its channel estimation (CE). The weighting coefficients on the channel condition can be updated using this unbiased CE method. Channel and noise statistics information are not essential. Rather, it uses a p

Although the two systems are very similar, the biggest difference of them is that LTE using SC-FDMA (single carrier frequency division multiple access) technique in uplink transmission. The advantage of LTE is to decrease peak-to-average power ratio (PAPR) which saves more power of the batteries of user equipments (UEs) and efficiently extends the using time, rather than using OFDMA (orthogo
