| Abstract: | The performance of Rake receiver is analyzed in the single user UWB communication system without ISI under IEEE 802.15.3a indoor channel model. The instance of Rake receiver is simulated under different channel conditions. The simulation of code - error rate for different Rake receiver structure is carded out. The results show that SRake is better than PRake＇ s and the performances of both receivers are improved obviously with more taps. The complexity of its realization is also investigated. |
