Texte intégralAn adaptive equalizer, based on a minimum mean square error criterion, has been derived for the purpose of extracting PSK signals transmitted through an unknown and asymmetric channel. The weights of the equalizer are obtained by using a simple formula containing the transform of the parallel channels. The performance of the equalizer is expressed in terms of the variance of the estimation error. The error is shown to be much less than that of the direct demodulated data.

Recent research has shown that the cooperative diversity can efficiently combat the fading effects caused by the hostile wireless channels just as the multiple-input multiple-output (MIMO) antenna systems do. Besides, due to the inherent cost and size constraints by many small area wireless networks, e.g. wireless ad hoc networks and wireless sensor networks, in such environments, it would be almost impossible to deploy the antenna array in a mobile node. However, cooperative diversity can provide an economical and viable solution by sharing each mobile node’s single-antenna with others to form a virtual antenna array, while it still can maintain significant performance gains similar to MIMO systems. Meanwhile, the adaptive modulation is a proven technique which can significantly increase the spectral efficiency when perfect channel estimation can be achieved, and many wireless standards have adopted it as an implementation option. It also has been shown that combining these two techniques can greatly raise the system efficiency. Nevertheless, in the multiple nodes cooperative communication networks, the randomness of demodulation process at each relay node makes the task of correctly selecting the forwarding relay nodes very complicated. In view of this problem, a novel adaptive node selection algorithm is proposed for the destination node to effectively select the forwarding relay nodes to help the source node transfer the signals. In this paper, the decode-and-forward (DF) protocol is employed as the cooperative diversity signaling, and the constant-power variable-rate M-ary phase shift keying (M-PSK) is adopted as the adaptive modulation scheme. At the destination node, the maximal-ratio-combining (MRC) method is used to combine all of the signals from diversity branches with the main path transmitted directly from the source node. Because of the random phenomenon of the demodulation process, the outage requirement is used as the baseline in the first stage of the proposed node selection algorithm to choose the maximal transmission rate. Hence the maximal overall system throughput in terms of rate can be achieved. In the meantime, the first candidate forwarding sets of the relay nodes which collectively meet the required outage probability are also been chosen. Then in the second stage, we can further refine the number of the relay nodes among the first candidate forwarding sets by using the following criterion — maximum average rate per node. It will screen out the first candidate sets with the minimum number of the relay nodes. If only one candidate set is left at the end of the second stage, it will be the end of the proposed algorithm. However, if the result of the screening still has more than one set, then the final election among the second candidate sets would be the one which can give the minimum outage probability. In the simulation results, our proposed node selection algorithm can even further improve the spectral efficiency while the deleteriously fading effect induced by the wireless channels can also be effectively removed.

Texte intégralO constante crescimento de aplicações Internet têm vindo a contribuir para a necessidade do aumento de largura de banda na rede de acesso, o que fomenta a procura de novas soluções para redes de acesso de fibra óptica. Nesse contexto, soluções conhecidas como transmissores independentes do comprimento de onda (WIT wavelength-independent transmitters) isto é, soluções para emissores que possam operar numa ampla gama de comprimentos de onda, poderão ser muito úteis. Sendo uma das mais promissoras o amplificador óptico semiconductor reflectivo (RSOA). Nesta dissertação foi implementado um modelo simplificado do RSOA que permite eficientemente determinar as suas características estáticas e dinâmicas. Foi também implementado um modelo de simulação, em Matlab, que permita estudar o desempenho de um sistema de comunicação por fibra óptica que utiliza RSOA e técnicas de modulação digital por desvio de fase com M estados (M-PSK M-ary Phase Shift Keying). Com o modelo de simulação foi avaliada qual a taxa de transmissão máxima atingível. A avaliação do desempenho foi feita através do cálculo da magnitude do vector erro (EVM Error Vector Magnitude), considerando os vários blocos implementados. Foi determinado o ponto óptimo de funcionamento do RSOA, sendo também avaliado do desempenho de sistema de transmissão, usando diferentes parâmetros do sinal M-PSK (M=4,16,64) com taxa de transmissão de 1Gbits/s e 10 Gbits/s considerando vários comprimentos de fibra óptica.
With the increasing need for consumers to benefit from an increased bandwidth, the demand of new solutions for access networks is increasing. In this context, solutions known as optical wavelength independent transmitters (WIT), that can operate over a wide range of wavelengths are envisaged, being one of the most promising based on the use of reflective semiconductor optical amplifiers (RSOA). In this dissertation, a simplified RSOA model was implemented. It was also implemented, in Matlab a simulation of an optical fiber optics communication system that employs directly modulated RSOA using M-PSK M-ary Phase Shift Keying. Using the simulation model the performance of the system was evaluated in terms of error vector magnitude (EVM). The operational optimum parameters of the RSOA where determined considering different bit rates and PSK constellation order. The system was evaluated for M-PSK (M=4,16,64) , 1 Gbits/ and 10 Gbits/s.
