In TD-LTE system, RACH (Random Access Channel) process is an important process for gaining time-frequency resource of uplink. Through the research on RACH signal detection, a low-complexity implementation approach is proposed in this paper. After research and analysis of RACH signal time domain detection algorithm and RACH signal circulate correlation algorithm based on Fast Fourier Transform (FFT), According to the Zadoff-Chu (ZC) sequence character, RACH signal circulate correlation on detection algorithm based on frequency domain ZC is proposed in this paper .Combined with different algorithm, the algorithm is proposed in this paper can rapid and effective realize RACH signal detection.
