Error Rate Analysis of PL Decoder in Dual Hop Dual Path Differential Cooperative System

Author : Akhil Adlakha 1

Date of Publication :13th June 2017

Abstract: In this paper, we consider a Dual Hop Dual Path decode and forward based differential cooperative system and we derive the conditional probability density function (pdf), conditional cumulative distribution function (cdf) of the Piecewise Linear (PL) approximation of the decision variable of each Relay-Destination link used in the system. Utilizing this, we have also derived the average Bit Error Rate (BER) of the PL approximation for the case in which one of the Relay is in outage as compared to the other Relay and the data is received at the destination from the Relay closed to the source
