摘要：
LTE-A ([1]) (Long Term Evolution Advanced) is a subsequent evolution of LTE. Compared with LTE, LTE-A will support a larger bandwidth, higher spectrum efficiency and higher peak rate. LTE-A introduce carrier aggregation, multi-point collaborative transmitting/receiving, multiple antennas, wireless relay and other key technologies. LTE-A uses the key technology of much higher levels of MIMO, and improve the anti-interference ability of system. Based the Successive Over-relaxation iterative algorithms, this paper pro posed an improved LMMSE algorithm. Simulation results show that improved LMMSE method can not only reduces the implementation complexity, but also has superior performance.
