Wireless communication is experiencing a proliferation in technologies and standards worldwide. This is expected to continue in the future. In addition to existing second generation cellular networks, third generation cellular systems and WLAN technologies are currently being deployed, allowing higher data rate communications. The concept of a multimode transceiver, which can simultaneously operate within cellular, and WLAN environments becomes increasingly significant as these technologies become more popular. Software radio is a potential solution for the implementation of reconfigurable transceivers, thus allowing the provision of services using different access technologies. This paper considers a multimode receiver architecture, based on bandpass sampling, suitable for operation in cellular and WLAN systems.
