摘要:

提出了两跳中继通信系统均衡和预编码一种联合优化方法,该方法在中继节点上把源节点与中继节点通信的检测算法和中继与目的节点 通信的预编码算法结合起来,从而联合优化问题就等效成对检测和预编码矩阵的乘积进行单一优化问题,克服了传统联合优化带来的非凸优化 问题,也克服了迭代算法可能带来的不收敛性,与迭代算法相比较,在复杂度上可以大大降低,通过仿真分析,可以看出性能上并没带来多少 损失,达到性能与复杂度的良好折衷。

Abstract:

An Optimal Equalization and Precoding Joint Optimization Algorithm in Dual Hop Relay System Abstract: A novel detection and precoding joint optimization algorithm was proposed in dual hop relay communication systems,this solution combines the detection for the first phase and precoding for the second phase in relay system, therefore the joint optimization can be equaled to the unique optimization for the product matrix of detection and precoding, and avoid the non convex optimization for commonly joint optimization, and also avoid the non-convergence problems in iterating process,and compared with iterative optimization, the complexity burden of this algorithm is greatly reduced, and from simulation results the performance is only a little degraded, therefore, when complexity and performance is considered, this algorithm reached a better compromise
