Title
Pulse repetition based selective detection scheme for coherent IR-UWB systems
Abstract
We propose a selective detection scheme based on pulse repetition for coherent IR-UWB (Impulse Radio-Ultra Wide Band) systems. For signal modulation and demodulation, we consider bi-phase modulation and on-off keying that are widely used in the coherent IR-UWB systems. The proposed selective detection scheme transmits the UWB signals by pulse repetition at the UWB transmitter to take system complexity into account, like conventional PRC (Pulse Repetition Coding). However, the proposed scheme performs selective detection by estimating the SNR (Signal-to-Noise Ratio) of the received pulse-repeated signal to effectively improve BER (Bit Error Rate) performance at the UWB receiver, unlike the conventional PRC. Simulation results in the IEEE 802.15.4a channel models reveals that the proposed scheme effectively improves BER performance of the coherent IR-UWB systems without much increment of system complexity, as compared to the conventional PRC.
