Error probabilities for sequency majority multiplexing in frequency-nonselective, slowly fading channels. 2. Numerical analysis
In this paper we have analysed the error performance of both the sequency majority multiplexing (SMM) and the concatenated sequency majority multiplexing (CSMM) schemes in the traditional AWGN channel and in a selection of frequency-nonselective, slowly fading channels. Our analysis extended the current knowledge on how these sequency multiplexing schemes perform in fading channels-an environment pertinent to the operations of wireless communication systems. We also looked at the improved performance of the CSMM scheme and revealed how such a simple improvement can further extend the performance gains of the SMM scheme by 2 to 3 folds. Our analysis highlighted a few attractive features of both the SMM and CSMM schemes which make them possible contenders for regulating multiple access in a multi-carrier spread spectrum scenario.
