In this paper, a binary hypothesis distributed detection problem in correlated wireless sensor networks with cooperative relays deployment is considered. In particular, the effect of correlation between sensor nodes is modeled and analyzed in Rayleigh flat fading channels in order to explore the natural tradeoffs between the number of sensor/relay nodes and the detection error performance in the network...
In this paper, we investigate the application of a unipolar non-coherent M-ary orthogonal keying (NC-MOK) for OFDM system that does not require channel estimation and compare its performance with that of bipolar Coherent MOK where for the latter phase information is obtained via pilot-based channel estimation. The performance of the orthogonal M-ary schemes concatenated with Reed-Solomon (RS) codes...
The use of pilot signals for the purpose of channel estimation in multicarrier systems does not only consume bandwidth but also signal power that could otherwise be invested in the information symbols to be transmitted. The aim of this paper is to investigate the issue of optimal transmitter power distribution between the pilot and information signals and evaluate its impact on the performance of...
