Abstract

Coordinated Multiple Point (CoMP) transmission is considered as one of candidate technologies for LTE-Advanced. CoMP improves average cell-edge user throughput as well as cell throughput and ensures the fairness of all uses. There are two categories in CoMP, Joint Processing (JP) and Coordinated Scheduling/Beam forming(CS/CB). In this paper, a novel precoding schemes based on Tomlinson-Harashima Precoding (THP) was proposed for JP. The proposed scheme aimed to minimize the error probability of the overall system by nonlinear processing and jointly ordered channels decomposition in the base stations. Simulation results show that this scheme has a significant gain over existing schemes in terms of system error rate.
