Abstract :
Considering ISI brought by high transmission rate in short-range IR-UWB, this paper proposes innovative low-complexity equalization for high data rate on-off keying IR-UWB energy detection (ED) receiver capable of eliminating ISI. We propose second-order Volterra model equalizer to eliminate ISI, and innovative approximate improved linear equalizer which has low complexity. The simulation results show that the performance of linear equalizer approximate the performance of non-linear second-order Volterra equalizer, and linear equalizer low complexity, fast convergence, make it very suitable for high data rate OOK-ED-IR-UWB practical application.
