This research work presents the design and the physical implementation of a power aware FFT core for OFDM-based, dynamic spectrum access (DSA) enabled cognitive radios. The FFT core is equipped with a pruning engine that allows the run-time removal of dummy operations (e.g. multiplications by a zero term) related to the pruning of sub-carriers of the communication systems. The pruning algorithm introduced...
The modern wireless standards predominantly are based on OFDM communication systems. Various mobile devices in recent times support multiple wireless standards and demand efficient transceiver. Hence, in a communication transceiver the baseband hardware needs to be scalable and efficient across multiple standards. In an OFDM based transceiver, FFT computation is one of the most computationally intensive...
