摘要

提出了一种新的空时分组码——ABCD码。ABCD码结合了Alamoutipsilas码和线程代数空时分组码的结构特点，具有全分集特性，传输速率为每信道2个码元，使用4个发射天线。ABCD码由于具有充分的传输分集，在高信噪比下具有良好的性能，并且具有较大的二阶互信息，保证了在低SNP下具有优越的性能。

A new space-time block code for high-data rate and full-diversity MIMO systems

A new space-time block code, named ABCD code, is presented in this paper. ABCD code combines the structure characteristics of the Alamoutipsilas code and the threaded algebraic space-time block code and has full-diversity, whose transmission rate is 2 symbols per channel use for four transmit antennas. Because of full transmit diversity, ABCD code can provides a good performance at high SNR and also has larger second-order mutual information which guarantees a superior performance at low SNP.
