摘　　要：文中提出了一种简单的基于准正交空时分组码的发送天线联合编码选择算法,该算法基于最小化误比特率的准则,通过迫零接收。仿真表明,该算法能够增加准正交空时码的分集增益和编码增益,降低误比特率。与最优的算法相比,复杂度降低,性能相近。This paper proposes a simple algorithm based on transmitter antenna/code selection combined with quasi-orthogonal space-time codes. The algorithm, based on the cirterion for minimize the Bit Error Ratio through zero forcing reciever, can provide additonal diversity gain and coding gain, and reduces the BER. As compared with the optimum algorithm, it reduces the complexity and provides the near-perfect performance.
