一种适用于超宽带的MRC-PRC判决反馈滤波器
MRC-PRC decision feedback filter for impulse radio UWB systems
【摘要】 针对超宽带无线通信系统提出了一种MRC-PRC判决反馈滤波器。对于系统的信干噪比以及误比特率性能进行了理论分析,并给出了计算机仿真验证结果。结果表明跟传统的MRC-PRC相比,MRC-PRC-DFF能获得3dB的信干噪比增益;此外,MRC-PRC-DFF跟性能优越的MMSE-PRC相比,系统的复杂度大大降低。
【Abstract】 A MRC-PRC decision feedback filter(MRC-PRC-DFF)for UWB wireless communication systems is proposed in this paper.SINR and BER for the proposed system are analyzed,and computer simulation results are verified.Compared with the conventional MRC-PRC,MRC-PRC-DFF can get 3dB SINR gain.Moreover,compared with the MMSE-PRC with similar performance,the computational complexity of MRC-PRC-DFF is greatly reduced.
