Channel estimation is one of the important modules of the receiving end in the LTE-TDD system,and it has great impact on the system performance.This paper introduces the generation detection methods and the location of time-frequency mapping of demodulation reference signal and reference signal in the uplink channel of LTE-TDD system.Through evaluating the performance of the hardware,a program for uplink channel estimation with the domain-based LS algorithm was proposed.This program can meet the requirements of real-time processing and provide better performance through the analysis of the complexity and fixed-point computation errors.
