An IR-UWB Receiver Design for Low Cost Applications

In this paper we present an energy collection based non-coherent low power and low complexity IR-UWB (Impulse Radio Ultra Wide Band) receiver which is robust against multipath fading. The proposed receiver adopts an integrator, a 1-bit sampler and a digital symbol synchronizer replacing with a classical RAKE structure, a high complex ADC and PLL respectively. Since the receiver is composed of such simple modules, we can reduce the total cost drastically. The performance of the proposed receiver is simulated based on IEEE 802.15.4a channel model.
