BEP Performance Analysis of Multi-Node Self Encoded Spread Spectrum - Cooperative Diversity in Rayleigh Fading Channel

Abstract

Self - encoded spread spectrum (SESS) is a novel modulation technique th at acquires its spreading sequence from the random input data stream rather than through the use of the traditional pseudo - noise code generator. It has been incorporated with multi node cooperative diversity systems as a means to combat fading in wireless channels. In this paper we analyze the cooperative SESS for Amplify and Forward CD links ( M SESS - AFCD) and SESS for Decode and forward CD links ( M SESS - DFCD) in Rayleigh fading channels. The BE P expressions are derived in closed form, and the veracity of the analysis is confirmed by numerical calculations that demonstrate excellent agreement with simulation results.
