In optically routed networks, information for verifying network configuration is not readily available in electronic form. To address this problem, a low-cost all-digital system was developed in [1], [2] for overlaying a low-rate management data channel on a high-rate payload data channel. In this work, we analyze the performance of this novel multi-user communication system under chip-level asynchronism, extending a previous analysis under chip-level synchronism. Two decoding strategies are investigated: a zero-forcing and a minimum mean-squared error detector. Fundamental tradeoffs among several system parameters are identified.

Abstract

In optically routed networks, information for verifying network configuration is not readily available in electronic form. To address this problem, a low-cost all-digital system was developed in [1], [2] for overlaying a low-rate management data channel on a high-rate payload data channel. In this work, we analyze the performance of this novel multi-user communication system under chip-level asynchronism, extending a previous analysis under chip-level synchronism. Two decoding strategies are investigated: a zero-forcing and a minimum mean-squared error detector. Fundamental tradeoffs among several system parameters are identified.
