提出了基于最小均方误差(MMSE)的异步跳频多址同信道干扰消除算法,利用接收信号的差异性,以及期望用户信号的一致性,对译码时频矩阵进行求和判决和最小方差判决。并采用迭代算法进一步提高检测性能。仿真结果表明该算法具有较好的性能,且收敛性好。
An MMSE - based asynchronous channel hopping multiple access co-channel interference cancellation algorithm is proposed. By using the difference of received signals and the consistency of expected user signals, summation decision and minimum variance of decoding time-frequency matrix judgment. And using iterative algorithm to further improve the detection performance. Simulation results show that the proposed algorithm has good performance and good convergence.
