In this paper, the dual mode receiver for wide and narrow band wireless system is investigated. In the current wireless system like GSM and WCDMA, the receiver base station should extract the individual radio channels from digitized wideband signal at extremely high sampling rate. However, the base station receiver must be capable at the same time isolate multiple channels from different bandwidths equivalent to channel bandwidths of different communication principles. The key requirements of current wireless systems are the reconfigurability and low complexity.
