能量包络的简单TOA估计研究
Simple energy envelope TOA estimation algorithm
摘要
Abstract
In IR-UWB(Impulse-Radio Ultra Wideband) ranging system, the current TOA estimation algorithms based on matched filter have their own shortcomings, like high complexity, large amount of computation and so on. This paper presents a TOA estimation algorithm based on energy envelope TOA estimation. This algorithm mainly detects the maximum point of the correlation output. The inputs of correlation are received multi-path signal and saw-tooth wave. The amount of algorithm computation is greatly reduced, and simulation results show its effectiveness. This paper compares this algorithm with TOA estimation algorithms, and the analysis of the algorithm error performance is presented.关键词
