X信道中一种新的空时编码传输方案
New space-time coded transmission scheme for the X channel
摘要
Abstract
A new space-time coded transmission scheme is proposed for the X channel with four antennas at each user who employs the rate-2 space-time block code.Each codeword is pre-coded,and then the addition and subtraction combinations of each codeword after pre-coding are transmitted separately.The number of interferential coding matrices is reduced through addition and subtraction operations of the received signals,and then the multi-user interference is eliminated by proper pre-coding at the transmitters and linear processing at the receivers.Compared with the existing scheme,the proposed scheme not only greatly reduces the feedback amount,but also significantly improves the system reliability.关键词
