摘要：The UWB (Ultra Wideband) technology has drawn phenomenal interest in industry as well as academia. Ultra Wide Band impulse radios are microwave systems that communicate using baseband pulses of very short duration. UWB systems transmit information data over a wide frequency spectrum with low power consumption and high speed for local area wireless network applications. Unlike the traditional digital communication method based on a carrier wave, UWB is pulse based. Pulse Generation, modulation, and multiple access are time domain dependent functions. This paper presents the development of analytical model for UWB system. A theoretical reference for UWB system performances is designed in non-ideal channels. In this mathematical models for biphase, pulse–position and hybrid modulation are developed. The detection rules are formulated for detecting signals in AWGN channels. The performance of UWB system is described with the help of BER. The BER of a UWB system depends on the modulation scheme and detection method it uses. It is observed that for optimum performance modulation parameter selection is important.
