Both Xilinx and Altera have released SoCs that tightly couple programmable logic with a dual core Cortex A9 ARM processor. These SoCs show promise in accelerating applications that exploit both the FPGA's parallel processing architecture and the CPU's sequential processing. %Spectrum sensing in cognitive radios is one such application. For example, before accessing a wireless channel, a cognitive...
The FPGA is an integral component of a software defined radio (SDR), which provides the needed reconfigurability for dynamically adapting its transceiver and data processing functions. The current state of the art in SDR design relies on complete processing of the raw samples at the host computer, thereby impacting time critical tasks. Instead, we propose to move the processing closer to the front-end...
Cognitive radio (CR) allows a pair of wireless communicating devices to intelligently adapt their transmission parameters based on the characteristics of the radio frequency (RF) environment, possibly using vacant portions of licensed frequency bands. A key step in this process is spectrum sensing, where the presence of primary users of the spectrum is detected by sending raw samples from the front-end...
