Addition of new bands, modes and services in mobile devices means the use of software defined radio (SDR) in the upcoming wireless devices is inevitable. To realize SDR, a common flexible hardware platform is required that supports transmission and reception of the existing radio access technologies. Air-interface and analog/digital conversions make a key part of SDR hardware both on transmitter and receiver. Front end processing block (FEP) of SDR consists of processing blocks required at the air-interface including Time/Frequency conversions, Dot-Products, Energy and Max calculations.We propose a flexible yet efficient hardware design for FEP that will furnish the front-end-functionality requirements of 2G, 3G, 4G, broadcast communication and wireless-LAN standards.
