摘要 介绍了球译码算法的工作原理,给出了算法流程;研究结果表明AWGN信道下LAS-CDMA系统使用16QAM调制时,球译码算法差错率趋近于使用基于ML算法的理论差错概率。 The principle of sphere decoding was introduced and the algorithm structure was also given. The result presents that when LAS- CDMA system using 16QAM modulation under AWGN channel, the error probability of sphere decoding goes to theory error probability of ML algorithm.
