Asynchronous trigger reception algorithm for low-power UWB system

A novel UWB pulse reception algorithm namely asynchronous trigger is presented, aimed at realizing a low-power and low-complexity system. Based on theoretical derivation and simulation results, when receiving UWB pulse signal with the asynchronous trigger algorithm at bit-error probability of 10^-5, the system´s processing energy decreases by 10dB at the cost of signal´s transmission energy increasing by about 0.5dB only. A transceiver based on the proposed reception algorithm is fabricated in CMOS technology, the experimental results also proves that the asynchronous trigger reception algorithm can lead to low-power low-complexity UWB systems implementation.
