| Abstract: | In this paper, it proposes a low-complexity quasi-optimum multiuser detection algorithm. This approach guarantees to converge the global optimum under the computational complexity of polynomial, which can efficiently solve the nondeterministic-time hard problem in the maximum likelihood multiuser detection. Simulations show that the proposed method has lower complexity and can offer good performance. |
