LTE-A系统中基于扩展CP的Rank 3-4解调参考信号设计
Rank 3,4 demodulation reference signal design based on extended CP for LTE-A
摘要
Abstract
To support the higher-order multiple input multiple output (MIMO) technology in 3GPP' S Long Term Evolution-Advanced (LTE-A) , a new pattern of Rank 3,4 DMRS (demodulation reference signal) was designed for physical downlink shared channel (PDSCH) based on the extended cyclic prefix (CP). The principles for design of reference signals based on extended CP were introduced. Then, the design pattern for Rank 3 ,4 reference signal based on the extended CP was proposed according to the decided patterns based on the normal CP. The mean squared error ( MSE) performance and the block error rate ( BLER) performance of the proposed DMRS patterns in the channel estimated and ideal channel were compared by simulation, and the optimum pattern was obtained accordingly.关键词
