摘要
提出一种改进型正交分组空时码(ISTBC),它能有效的提高编码增益,克服原有正交分组空时码(OSTBC)在多天线(大于2)、复信号时不能实现全速传送的缺点。ISTBC在接收端采用复杂度适中的复球包线译码。
An improved orthogonal space-time codes （ISTBC） design method is given in this paper. It can effectively imporve the coding gain, and can overcome the drawback of not being able to transmit with full speed in the cases of multi- antennas （more than 2） and complex signals with original OSTBC. It applies Complex Sphere Decoding （CSD）, which is of medium complexity at the receive end.
