In this paper, a novel general design method of quasi-orthogonalspace-time block codes for four antennae is presented.

Whereas the non-orthogonalspace-time block codes which obtain higher transmission rate at the cost of orthogonality and partial diversity gain may degrade the performance.
而以牺牲正交性和部分分集增益为代价来获得更高传输速率的非正交空时分组码又会使误码性能降低。

Focusing on the problem that existing linear dispersion (LD) space-time codes have a high encoding and decoding complexity, a type of orthogonal linear dispersion (OLD) space-time codes is proposed.
