| () |
| Abstract: |
| The time delay estimation problem for multipath signals in wireless communication is discussed. For the receiver using antenna array, an efficient time delay algorithm based on the nonlinear least squares criterion is proposed. Simulation results show that reasonable performance can be obtained by using the proposed algorithm. |
