Abstract
Low rate ultra-wideband (LR-UWB) system requires a simple and cost-effective transceiver architecture to establish nodes in future sensor network. To satisfy this requirements, the simple noncoherent on-off keying (OOK) UWB transceiver with the parallel energy window banks (PEWB) giving high precision signal processing interface is proposed. The flexibility of the proposed system in multipath channel environments is acquired with the pulse and bit repetition method. To analyze the bit error rate (BER) performance of this proposed system, a noise model in receiver is derived with commonly used random variable distribution, chi-square. BER of 105 under the line-of-sight (LOS) channel environment is achieved with the integration time of 80 ns and signal to noise ratio (SNR) of 16.3 dB. This electronic document is a "live" template.
