Owing to the advantage of simple circuitry, energy detection based weighted non-coherent receivers (WNCR) have been motivated for impulse radio ultrawideband (IR-UWB) systems in recent years. With an aim to combat the practical channel impairments of different levels, this paper further investigates the combining weights of the WNCR, ending up with two blindly weighted non-coherent receiver (BWNCR)...
This paper proposes a maximum eigenvector based weighted non-coherent receiver (MEV-WNCR) for impulse radio ultra-wideband (IR-UWB) systems with pulse position modulation (PPM). Capitalizing on the SNR maximization criterion, we derive the optimal combining weights for the MEV-WNCR as the maximum eigenvector of the received signal sample covariance matrix. Unlike the conventional WNCR, the a priori...
