摘要：

The performance of code-division multiple access (CDMA) as a multiple-access technique for optical wireless communications is evaluated. The information data is modulated through dual-amplitude pulse interval modulation (DAPIM). Optical orthogonal code is used as the signature sequence. The upper bound and lower bound on the exact probability of errors per slot and per packet are derived in the presence of ambient background noise. We investigate the performance characteristics for various system parameters, including the SNR of the source information bits, receiver threshold, DAPIM order, and number of users.
