摘要
结合分布式空时码的系统模型和DBOAST空时分组码的编码方法,提出了一种新的分布式空时码——DBO分布式空时码(DBO-DST),可达到满发送分集度和满符号传输率。对该分布式空时码的编码和解码方法进行了仿真,结果表明,DBO分布式空时码比已有的线性分布式空时码的误码率低,性能更优。
A new family of distributed space-time codes is constructed in this paper, called diagonal block orthogonal- distributed space-time codes which combined distributed space-time code model and diagonal block orthogonal algebraic space-time codes. It can transmit at a normalized rate of 1 symbol per channel use. It is proved that it can achieve the full transmit diversity. The performance merit of DBO-DST codes is confirmed by Monte Carlo simulations and compared with linear distributed space-time codes.
