A theoretical analysis of the performance of code division multiple access communications over multimode optical fiber channels .II. System performance evaluation

摘要

In this paper, we conduct a system performance evaluation of code division multiple access communications over multimode optical fiber channels. More specifically, we complete the task started in Part I of this paper. In our system evaluation, we consider a collection of independent users sharing a common multimode optical fiber channel, which obey a binomial channel access and utilization model. Under this model, the bit error probability at the ith receiver is calculated as a function of the peak receive signal-to-noise ratio; where the signal-to-noise ratio is a function of the number of active users, the bit energy over "white" noise spectral density, and the percentage time users are active. We also make a comparison of the performance of this system with that obtained for an ideal channel.
