In this chapter, we investigate the performance of symbol error of a multihop multilink cooperative relayed wireless network by deriving the symbol error probability (SEP) over a Rayleigh flat fading channel. We studied in two different system using decode and forward (DF) relaying model: (1) model of single branch multihop relaying without symbol error and (2) model of multihop multibranch relaying with symbol error in decoding. The expression for symbol-to-noise ratio at destination in terms of cumulative density function (CDF) and probability density function (PDF) are derived. The theoretical results of SEP are obtained by using MPSK modulation technique. The relay links are identically and independent distributed (IID). Monte-Carlo Simulator is used for verifying the analytical results and computer simulated results.
