The Performance of Frequency Comb Multiple Access(fcma) in Interference Limited and Awgn Environments

The performance of FCMA is analysed in environments where the dominant sources of interference are firstly, the multiple access noise of other users and secondly, AWGN. Ultimately, multiple access noise is the limiting factor in performance. The intended transmission to the selected addressee is always symbol synchronous and phase coherent. The interferers are observed in one instance when they are symbol synchronous and phase coherent and again while symbol synchronous but noncoherent in phase. The symbol synchronous phase coherent interferers are found to represent the worst case performance.
