The Simulation of DS-UWB RAKE Receiver over the Multipath Channel

Abstract:

Ultra-Wideband (UWB) wireless communication is a new potential communication technology currently in its field. It becomes very popular in the world since it’s high performance, low radicalization and low cost. Currently UWB wireless system, we can call it Impulse Radio technology too, be invented in 20 century 1960s. But it was only used in military affairs field, bailout searching, radar location and so on. After civil using, it usually is used in indoor wireless LAN .In this paper, the development and application of UWB are introduced, the characteristic and limitation of UWB are simply analyzed. According to the simulating depending on Multipath channel, it shows increasing SNR about 1.5dB to the base of primary power district or increasing SNR about 1dB to primary power district and minor power district, we can get whole performance of RAKE receiver in perfect channel.
