Performance comparison of Impulse Radio Ultra Wideband receivers

Abstract

Ultra Wideband (UWB) is a communication technique that uses a very narrow radio pulses for communication over a large bandwidth between transmitter and receiver. UWB technique is gaining popularity day by day because of its certain characteristics like simple architecture, cost reliability and low power consumption which is quite desirable in the field of short range wireless communication. Transmitting such a short duration pulses in a multipath environment create a critical problem in designing the transceiver for Impulse Radio (IR) UWB systems. Several research activities have been carried on for effective and efficient transmission of very short duration pulses for IR-UWB systems. Here, in the this paper, we presented a performance comparison between Transmitted Reference (TR), Multi differential frequency shift reference(MD-FSR) and code shift reference (CSR) which are the three primary pulse sending techniques in UWB communication. These techniques have been evaluated by comparing its systems BER performance. Simulations have been performed in MATLAB. The simulation results validate that CSR-UWB system has a better BER performance compared to TR and MD-FSR UWB systems under the desired parameters.
