| Abstract: | This paper mainly examines the effects of laser phase drift on the performance of CDMA system using BPSK and DPSK modulation. Under the existence of AWGN, multiple access interference (MAI) and laser phase drift, the experssions of error probability of two detectors (matching filters and decorrelating detector) for BPSK and DPSK are derived. |
