摘要
本文采用分圆格方法,设计了一种简化型具全分集、满速率特性的四发四收准正交空时分组码。该准正交空时分组码不仅比传统的基于星座调制技术的四发四收准正交空时码具有更大的分集增益上界,而且比已有的八发一收分圆准正交空时码在误码率和信道容量、以及中断概率等方面皆具有显著的优越性。
In this paper, we use cyclotomic lattice method to design a simplified type quasi-orthogonal space-time block codes with full-diversity, the full-rate characteristics on four transmit and four receive antenna. The quasi-orthogonal space-time block codes not only have a greater the upper bound about diversity gain than the traditional constellation modulation technique about quasi-orthogonal space-time code with with four transmit and four receive antenna, but also have significant advantages in code error rate and channel capacity, and outage probability than the existing eight transmit one and receive quasiorthogonal space-time code.
