Abstract
This paper presents a noncooperative distributed amplify-and-forward (AF) single-input multiple-output (SIMO) wireless relay networks under two adverse wireless communication environments: (1) node geometry and a jamming environment, and (2) channel uncertainty and a jamming environment. All relay nodes in wireless relay networks cannot exchange their received signals from source nodes for relay noncooperation. The main contribution of this paper is the derivation of an optimal diagonal amplifying relay matrix in AF SIMO wireless relay system using the minimum mean square error (MMSE) criterion. To evaluate the effects of two adverse wireless communication environments on the AF SIMO relay scheme, simulation results are presented for a system using the derived optimal diagonal amplifying relay matrix with bit error rate (BER). In addition, performance comparisons under no node geometry, no-jamming environment, and no channel uncertainty were also considered.
