  • Based on Ultra-WideBand (UWB) conventional Transmitted Reference (TR) technology, the interference model which reference and data receive waveforms are both contaminated by inter-pulse interference is analyzed relying on Time Division Multiple Access. On account of the slow varying character of the UWB channel, some non-overlapped pilot pulses are utilized to estimate the model coefficients, and the coefficients are tracked by Volterra LMS algorithm. A root method is adopted to equalize the second-order non-linear inter-symbol interference. Simulation result in IEEE 802.15.3as indoor multipath channel model shows that the non-linear equalization receiver can eliminate the ISI better than linear equalization receiver.
