In this paper it is investigated the non-coherent demodulation of the 2PPM modulated UWB signal, based on energy-detection. This type of demodulation leads to a simple receiver architecture, low power consumption and the benefit of multipath energy capture. However, this technique is very sensitive to noise and channel interference. To minimize this drawback, optimizations have been proposed with respect to the reduction of the integration windows size and bandwidth of input matched filter. An appropriate ultra-wideband multipath channel model such as IEEE 802.15.3a may be considered for this optimization process. Basic method uses a single integration window with a constant gain, capturing only significant useful power of the signal replicas presented in the front of the received signal, and neglecting later signal. Instead of a rectangular integration window, it is proposed to use an integration window with a linear descending gain. This may be simply obtained by adding a supplementary integration block. In this way, the front-side useful signal power is integrated with a better gain in comparison with later, predominant noise, received signal. The simulations show an improvement in bit error rate performance relative to the basic method of energy-detection.
