A COMPARISON OF THE DELAY SPREAD OBTAINED WITH DIFFERENT POWER DELAY PROFILES DENOISING TECHNIQUES

Power delay profiles are determined by the processing of data from measurements carried out in a wideband channel. They are contaminated by the channel and the receiver noise and then they need to be de-noised in order to determine the dispersion parameters of the channel. In this paper, three different de-noising techniques are applied to choose the valid multipath in the noisy power delay profiles. The delay spread parameter is determined and the results are evaluated by comparing them with those obtained with the dirty profiles.
