Optimal power allocation and relay selection for multiple code division multiple access peer‐to‐peer communication

Application of best relay selection approach to cooperative DF IDMA systems over Rayleigh/Weibull fading channels

“…The references given by previous studies have analyzed various performance metrics for a conventional cooperative system without considering well‐known wireless communication systems such as cognitive radio, code‐division multiple‐access (CDMA), multiple‐input multiple‐output, space‐time network coding (STNC), and interleave‐division multiple‐access (IDMA) systems. On the other hand, there are several works in the literature that dealt with cooperative communications using the above mentioned systems . While a novel analytical expression for the OP of the DF cognitive radio networks with RS scheme was obtained in Chen et al, optimal power allocation and RS for a CDMA system have been discussed in Lashkari et al The authors in Lashkari et al proved that the relay gain and the total transmit powers remain unchanged.…”

The authors of Kapucu et al examined BEP, OP, and channel capacity analysis of direct‐sequence CDMA systems with AF relaying over dissimilar fading environments.…”
