广义常规球形解码算法能处理多输入多输出系统(Multiple-Input Multiple-Out-put,MIMO)中发送天线多于 接收天线的情况,但是对于非等符号能量的星座图,如正交幅度调制(Quadrature Amplitude Modulation,QAM)运 算量大。为了进一步降低算法复杂度,提出一种改进的快速算法,该算法采用了预处理排序策略和广义球形解码 与迫零检测结合的搜索策略,从而避免了高复杂度。仿真结果表明该快速广义球形解码算法以较小的性能损失换 取明显的复杂度减少。

Quadrature amplitude modulation (QAM) is a modulation scheme in which two sinusoidal carriers,
one exactly 90 degrees out of phase with respect to the other, are used to transmit data over
a given physical channel. One signal is called the I sign
