In recent years, RF receiver designers focused on replacing analog components with digital ones, trying hard towards the ideal Software Defined Radio (SDR) where all signal processing is done in software. Such an ideal SDR platform may form a flexible and reprogrammable receiver that can deal with many different standards, e.g., IS-95, GSM, UMTS, and especially the various military standards. A wideband receiver has to simultaneously deal with hundreds to few thousands channels, which lay in the same spectrum interval. One of the most computation intensive tasks in such receiver is channelization . A wideband channelizer decomposes its RF input signal into separate outputs, each containing the signal of single channel. The goal of the presented research is to study algorithms for wideband channelization then we compare the introduced algorithms.
