Abstract

A novel algorithm aligning the time-delay of each signal received by a uniform antenna array is presented. In order to solve the problem that time-delay alignment performance is poor at the low signal-to-noise ratio (SNR) value, the proposed algorithm makes use of iterative estimation. Then we analyze and compare the performance between the proposed method and the time-delay alignment algorithm based on quasi synthesis reference (TAQSR), indicating that the new algorithm has better performance. Simulation results show that the new algorithm not only improves the time-delay alignment performance in the multi-antenna signal synthesis system, especially in low SNR, but is also free from the actual value of the time-delay difference, compared with TAQSR.
