[ED: Softcover], [PU: VDM Verlag Dr. Müller], In a power constrained relay network environment, theperformance can be improved by using variousforwarding techniques and position dependent optimalpower allocation strategy. We use our three terminalmodel to optimize the power allocation under totaltransmit power constraint, to maximize theinstantaneous signal-to-noise ratio (SNR) atdestination, and thus achieve improved throughput andBER performance, while using AF and DF protocols. Weevaluate the performance of our system for bothcoherent and non-coherent modulation in a Rayleighblock fading channel. QPSK is used in the coherentcase and 4-FSK is used in the non-coherent case. Wederive expressions for instantaneous SNR using ourmodel and optimize the power allocation based on that, thus achieving improved uncoded BER. We compare the performance of the AF and DF protocols based on their positional BER and throughput at different received SNR and notice that our power optimized schemes outperform existing power control schemes at certain areas. Finally we also identify the shape and area of the regions where relaying would provide performance gains for both theprotocols at different received SNRs. 2009. 100 S. 220 mm Versandfertig in 6-10 Tagen, DE, [SC: 0.00], Neuware, gewerbliches Angebot, Offene Rechnung (Vorkasse vorbehalten)<
