Abstract
A real-time symbol-optimum detection algorithm for a CDMA system is developed in this paper by a truncation in the backward schedule. Simulations are present to show that the proposed truncated symbol-optimum detection provides negligible performance loss compared to the original symbol-optimum detection. It allows a tradeoff between the latency, the computation load, and the performance. A systolic array implementation of the algorithm is derived to exploit the suitability of the algorithm for parallel processing. With such an implementation, the processing speed is greatly improved.
