Sensitivity optimization of WDMA networks with subcarrier control channels

In this paper, we analyzed and optimized different receivers used in WDMA networks with subcarrier control channels. For the first time, APD/APD and APD/PIN receivers are suggested and analyzed. The results show that for a reasonable number of stations, the new receivers will give 6 dB to 10 dB performance improvement over a conventional PIN/PIN receiver.
