【 摘 要 】

References(6)In this paper, we propose a novel sub-optimum detection technique for asynchronous multicarrier code-division multiple-access (MC-CDMA) systems. The proposed technique extracts desired user's bits by means of expectation-maximization (EM) algorithm considering outputs of subcarriers demodulators as observation data. Our presented numerical results demonstrate the efficiency of the proposed detection algorithm both in bit error rate performance and computational complexity points of view.
