Abstract :
Nonregenerative relaying in MIMO multi-relay networks is analyzed under the general operating scenario of independent but not necessarily identically distributed (i.n.d.) Rayleigh fading. Exact closed-form expressions are derived for the moment generating function of the end-to-end signal-to-noise ratio (SNR) with distinct average received SNRs in each link. Our analysis applies to arbitrary L number of relays, each equipped with arbitrary N transmit/receive antennas. Based on the derived results, we determine the symbol error rate with M-ary phase-shift keying. In addition, we carry out a high SNR analysis of the error performance. We explicitly reveal that the diversity order is equal to LN+1.
