摘要
对一种基于检测转发方式的酉空时协作分集技术进行了研究,该技术可以在发送端和接收端都不知道信道信息的情况下使数据可靠地传输。在该协作分集技术下,通过对2个用户协作系统进行仿真分析,结果表明,其误码率性能与每个用户的信道和用户间的信道相关。
A unitary space-time cooperative diversity based on detect and forward method was studied. It can be well-tailored for flat-fading channels where neither the transmitter nor the receiver knows the fading coefficients. Using the unitary space-time cooperative diversity, the simulation by two-user cooperative system was done. Simulation result shows that the bit error rate is dependent on the characteristics of the user's individual channel and the inter-user channel between them.
