Abstract :
A precise bit error rate analysis is performed for bandwidth-efficient dual-channel quadrature phase shift keying in Nakagami fading with Nakagami-faded asynchronous interfering signals. In contrast to previous works, the analysis accounts for the dependencies between the quadrature carriers owing to nonRayleigh fading and cochannel interference. The impact of the interfering users´ fading severities on the desired user bit error rate is investigated. A comparison of the bit error performance for binary phase shift keying and quadrature phase shift keying is given.
