However, the exist sphere decoding algorithm can not solve the system where there are more transmit antennas then the receive antennas.
但是常规球形解码算法不能解决发送天线大于接收天线的问题。
This paper focuses on the traditional detection techniques in MIMO systems, especially BLAST algorithm, and then studies the sphere decoding algorithm.
重点研究了MIMO系统传统检测技术，尤其是BLAST算法，其次还研究了球形译码算法。
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.
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。
