| Abstract: | This paper proposes a varying pilot power method for multi-path channel estimation based on first order statistics, derives the expressions of channel estimator and estimation variance, and gives some analysis on the performance of estimators and power loss, having no loss of information rates, and showing strong estimation robustness. Theoretical analysis and simulation results demonstrate the effectiveness of the method. |
| Keywords: | Channel estimation Power loss First-order statistics Robustness Pilot |
