摘要:
针对准正交空时分组码不能实现满分集增益的缺点,在星座旋转的基础上,将角度反馈引入到准正交编码中.改进后的空时分组码,可以在不降低码率的同时实现全分集,并且提出了一种量化方案,通过对干扰项的实部和虚部信息的简单比较选取来简化设计的复杂度,达到了在发射端仅仅需要少量的角度反馈信息就能有效对抗噪声干扰的目的.仿真证明这种简单的改进可以使系统的性能得到明显的提高.
Abstract:
Space time block coding (STBC) based on transmit diversity scheme is an important way to implement the MIMO system. The ABBA with constellation rotation has been improved when the angle feedback is brought in. The improved code can achieve full diversity gain while not reduce the code rate, so the information can be transmitted more quickly and reliably. Furthermore, a new quantification scheme is proposed. It decreases the complexity of the design through a simple selection between the real and imaginary parts of the interference. By this way, it only needs a little feedback at the transmitter to suppress the interference. Simulation showed the new code improved the system performance significantly.
