Investigation of the performance of a multimode, multiband receiver for OFDM and cellular systems

Third generation cellular systems are currently being rolled out worldwide. In addition, WLAN technologies such as Hiperian2 and the IEEE 802.11 family of standards are being introduced in many areas, allowing broadband 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 provision of services using different technologies, and the implementation of reconfigurable transceivers. This paper considers a multimode receiver architecture, based on bandpass sampling, suitable for operation in cellular and WLAN systems.
