Abstract :
In this paper a new parameter estimation technique based on channel impulse response estimation is introduced which is desirable in randomly time-varying systems such as burst transmission mobile systems since it is robust in environments with considerable delay spread, thus ideal for wireless channels, and has a fast convergence, thus desirable in burst transmission systems. The shortcomings of some of the existing algorithms are also discussed here
