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。

However, the exist sphere decoding algorithm can not solve the system where there are more transmit antennas then the receive antennas.

最后针对空频码解码采用最大似然译码复杂度较高的问题，给出了球形译码算法的详细步骤。

Last, for the problem that the high decode complexity of space-frequency code, detailed steps of sphere decode algorithm is provided.
