【摘要】 提出了一种简便易行的光同步CDMA多址干扰抑制方案。该方案采用修正的素数码，在每个用户的接收端设置一组相关器和一个排队网络。由于所采用的码的相关特性，这种算法利用了其他用户所包含的信息，对于发"0"时，能完全消除多用户干扰;对于发"1"时，除消除一部分干扰以外，可以大大减小误码概率。数值结果充分说明了这一点。更多还原

【Abstract】 In this papet, a simple optical synchronous CDMA multip]e access interference surpress and cancellation scheme are proposed. The system uses modefied prime code(MPC). Each user is set a bank of correlator and the correlator’s output power is queued in a network. Beacuse of the MPC’s correlation characteristics, muItiple user interference is surpressed. The algorithm can completely cancel multiple user interference when "O" signal is trasmitted. A part of multiple user interference cacelled as the remainder can enhance the user’s signal power when "1" signal is trasmitted. The numerical results show that this method can decrease the BER greatly.更多还原
