Abstract :
In coherent UWB receivers, creating a template to match the received signal exactly is usually difficult and costly. If a simplified template is employed, the receiver´s performance degrades due to the unmatched template. The paper proposes a pulse shaping optimizer with genetic algorithms to maximize the signal-to-noise ratio (SNR) of the received signals, and therefore reduce the performance degradation for an arbitrary receiving template in a UWB receiver. The pulse shaping optimizer is basically an all-pass filter.
