%X Inter Symbol Interference (ISI) will increase when transmission rate of an Impulse Radio-Ultra Wide Band (IR-UWB) system is getting larger, which will worsen Bit Error Rate (BER), restrict the highest realizable transmission rate. In order to suppress ISI and realize high transmission rate, based on the causation of ISI, a Fractionally Spaced-Decision Feedback Middle Equalization (FS-DFME) equalization receiver is proposed. The receiver can realize jointly Matched Filter (MF) and channel equalization so as to collect multipath signal energy and suppress ISI. Simulation results show that the observation window length is important parameter in mitigation of ISI. Compared with Linear Equalization (LE) and Fractionally Spaced-Decision Feedback Non-Middle Equalization (FS-DFNME) equalization receiver, ISI is mitigated more effectively by FS-DFME equalization receiver and BER performance is improved obviously.
