| Abstract(in English) | In this paper, we propose a multiuser detection algorithm for synchronous CDMA systems based on convex optimization. Though optimum multiuser detection has good detection performance, the optimum detection is computationally intractable. We formulate the multiuser detection problem as a quadratic programming problem by relaxing constraints of the optimum multiuser detection problem. The quadratic programming problem is solved with a primal path follwing interior point method. From some experiments, it is observed that the proposed method achieves smaller bit error rate than that of parallel interference canceller (PIC). |
