在空时分组编码（STBC）的MC－CDMA系统中，根据STBC正交编码的特点，提出了一种简单可行 的基于常模（CM）准则的盲多用户检测算法。该算法基于最小二乘常模算法（LSCMA）的盲多用户检测算法， 算法大为简化，抽头系数减少了一半，性能略有下降。

Utilizing the orthogonal feature of space time block coding ( STBC) ,  a simple and feasible algorithm based on constant modulus (CM) criterion is proposed for blind multi-user detection in STBC MC - CDMA systems. The algorithm proposed in the paper as a simplified version of the algorithm based on the least square constant modulus algorithm(LSCMA) has the advantage of half taps and therefore considerable reduced computation at the cost of a certain loss in performance.
