空时分组码（sTBc）能提供满分集增益和较低的实现复杂度，但是却无法获得编码增益，为了进一步提升性能，考虑将空时分组码与Turbo进行联合编码。文章介绍了空时分组码和Turbo码的特点，并给出了联合编码的结构。Matlab仿真显示，联合编码结构具备更优异的性能。
空時分組碼（sTBc）能提供滿分集增益和較低的實現複雜度，但是卻無法穫得編碼增益，為瞭進一步提升性能，攷慮將空時分組碼與Turbo進行聯閤編碼。文章介紹瞭空時分組碼和Turbo碼的特點，併給齣瞭聯閤編碼的結構。Matlab倣真顯示，聯閤編碼結構具備更優異的性能。

Space-Time Block Codes（STBC） achieves full diversity gain and low complexity, but it cafft obtain coding gain. In order to improve performance, Joint encoding of Space-Time Block Code and Turbo Codes is considered. In this paper, the specialty of Space-Time Block Codes and Turbo Codes is depicted, and Joint encoding structure is presented. Matlab simulation shows that joint encoding structure have better performance.
