Distributed Regenerative DF SISO Wireless Mobile Networks under PCSI and ICSI

Abstract

This paper studies the regenerative decode-and-forward (DF) for mobile wireless relay networks under perfect channel state information (PCSI) and imperfect channel state information (ICSI). The wireless mobile network under study consists of one-source-one-destination mobile pair and N-multibranch mobile relay nodes. The proposed detection tactics, employing the maximum ratio combiner (MRC) principle, are proposed for a mobile network experiencing either PCSI or PCSI. These tactics are applied at mobile relays and the mobile destination accordingly to optimally detect received signals. Using the proposed detection schemes, Monte-Carlo simulations are performed to evaluate the system performance for the distributed regenerative DF single-input single-output (SISO) mobile wireless relay network. Performance comparisons for cases, such as ICSI only in source-relay links and ICSI only in relay-destination links, were also included.
