使用3GPP10版本即LTE-A(Long Term Evolution Advanced)中新的参考信号,通过不同的信道估计算法来进行信道估计,然后对其性能进行了评估.信道状态信息参考信号被用来进行反馈估计,采用终端专用参考信号来进行解调.此外还对比了LTE中参考信号与LTE-A的参考信号的优缺点.最后给出了评估信道估计性能的仿真结果.%In this paper we apply and assess the performance of different channel estimation algorithms to the new reference signal structure standardized for LTE Advanced in the 3GPP Release 10 standards.The different reference signals are presented and they are employed to obtain channel estimates for demodulation and feedback calculation.Furthermore,we point out the advantages and drawbacks of the LTE Advanced reference signals in comparison to the LTE reference symbol structure.Finally we provide simulation results to evaluate the capabilities of the designed channel estimators.
