Abstract:
A cell search method for a multi-mode telecommunication apparatus is disclosed. The method comprises receiving signals present in a frequency range; transforming received signals into frequency domain; estimating power spectral density from transformed signals; estimating probability of different communication modes by correlating the estimated power spectral density with power spectral density signatures of said different communication modes; and performing cell search according to estimated most probable communication mode. Such an apparatus and a computer program for performing the method are also disclosed.
