Abstract :
Optimum selection combining using the maximum energy (OSC-ME) criterion for M-ary noncoherent frequency shift keying signaling in independent and non-identically distributed (i.n.d.) fading channels is examined. A weighted maximum energy selection combining (WMESC) scheme is proposed and found to provide the virtually the same symbol error probability as the OSC-ME in Rician fading channels. The WMESC always provides power gain over the classical selection combining (SC) regardless of diversity order and signal-to-noise ratio.
