Performance Analysis of Distributed CDD MC-CDMA Sensor Networks with Frequency-Correlated Subcarriers over Nakagami-m Fading Channels

Sensor networks as cooperative spatial diversity (CSD) is implemented and analyzed for cyclic delay diversity (CDD) distributed MC-CDMA system. In such as cooperative system, it is proposed a distributed SISO analysis employing CDD to simplify the system evaluation in terms of probability of errors and maximum achievable throughput [bits/s/Hz]. Furthermore, the moment generating function (MGF) of the correlated Nakagami-m random variable is used and considered for the realistic case of frequency-correlated MC-CDMA subcarries. To this end, an explicit allocation strategy for the distributed diversity is deducted. Simulation results are also presented which show excellent agreement with the analytical framework.
