摘要：

In this paper, we suggest an asynchronous microcellular CDMA system with a matrix-based multiuser interference canceler for the reverse link, in which multiuser interference is completely removed on a symbol-by-symbol basis. The linear interference cancellation scheme, whose matrix order is equal to the number of active users, does not require knowledge of their received power levels, thereby resulting in high capacity and near/far resistance. In this paper, the influence of surrounding cell interference on a given base station receiver for various propagation path loss models is also analyzed and then the system performance is investigated theoretically. Provided the normalized capacity is defined by a required SNR = E(b)/N(o)) of 7 dB at the binary DPSK detector, the CDMA system can provide capacity per cell of 46 approximately 54%.
