  Abstract

IEEE802.15.4a, which is started to realize the PHY layer including high precision ranging/positioning and low data rate communication functions, requires a simple and low power consumable transceiver architecture. 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 fading 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 5 10. under the line-of-sight (LOS) residential channel is achieved with the integration time of 32 ㎱ and signal to noise ratio (SNR) of 15.3 ㏈. For the non-line-of-sight (NLOS) outdoor channel, the integration time of 72 ㎱ and SNR of 16.2 ㏈ are needed. The integrated energy to total received energy (IRR) for the best BER performance is about 86%.
