Robust, efficient and low complexity design methodologies for high speed multi-band orthogonal frequency division multiplexing ultra-wideband (MB-OFDM UWB) is presented. The proposed design is implemented in 0.13μm CMOS technology with the core area of 2.66mm × 0.94mm. Operating at 132MHz clock frequency, the estimated power consumption is 170mW.
We have recently proposed a novel receiver for Ultra-Wide-band Impulse-Radio communication in bursty applications like Wireless Sensor Networks. The receiver, based on the principle of Compressed Sensing (CS), exploits the sparsity of the transmitted signal to achieve reliable demodulation. It acquires a modest number of projections of the received signal using analog correlators, and performs a joint...
Energy-detection is appealing for IEEE 802.15.4a receivers as it allows to exploit the ranging capabilities and the multipath resistance of impulse-radio UWB at a reasonable complexity. IEEE 802.15.4a receivers operate with interference created by uncontrolled piconets and an uncoordinated medium access control. Prior work showed that the performance of an energy-detection based receiver is greatly...
