摘要:
针对60 GHz芯片间无线互连信道中存在的多径衰落问题,将匹配滤波器和最小均方误差算法应用到60 GHz脉冲通信系统,重点分析多径信道下采用最小均方误差合并算法的RAKE接收机的误码性能。在IEEE 802.15.3c信道模型的基础上,对采用不同合并方式、不同干扰用户数目下的RAKE接收机误码性能进行了研究。仿真结果表明,随着干扰芯片数量的增加,引入匹配滤波器和最小均方误差算法的RAKE接收机不仅降低了接收机的采样率,而且有效提高了系统抗多用户干扰的能力,为芯片间无线互连系统的RAKE接收机设计提供了技术参考。

Abstract:
To solve multipath fading problems in 60 GHz inter-chip wireless interconnect system,matched filter and minimum mean square error(MMSE) algorithm are applied to 60 GHz impulse communication system,and the bit error rate(BER) performance of MMSE-RAKE receiver is researched. Based on the IEEE 802.15.3c channel module,the performance of RAKE with different weighted consolidation strategies and interference users is analyzed. The simulation results show that,with the increasing of interference users,the MMSE-RAKE receiver with matched filter and MMSE not only effectively reduces the sample rate of receiver,but also improves the anti-multiuser interference ability of system. The research provides the technical reference for RAKE receiver design of inter-chip interconnect system.
