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
