摘要

针对60 GHz芯片间无线互连系统中信号幅度衰落及多径时延，导致信道产生突发性错误引起误码率增大的问题，从编码增益和译码能耗角度研究了该系统中卷积码的性能。根据60 GHz芯片间无线互连系统特点，分析了适用于此场景的CM7.2信道特性以及编码系统接收信噪比。结合信道编码理论，推导了卷积码的临界距离，得到了编码系统的能效衡量标准。在此理论研究的基础上，通过MATLAB对卷积码进行了蒙特卡洛数值仿真，得到了编码增益，进而分析了最大通信距离。通过QuartusⅡ对卷积码进行了电路能耗仿真，得到了编译码能耗，进而分析了临界距离。综合考虑卷积码的编码增益、译码能耗及有效通信距离，提出了可优先采用的编码方案。为60 GHz芯片间无线互连系统以及其他60 GHz近距离无线通信系统提供了纠错编码方面的技术参考。

Abstract

In order to solve reliability problem in 60 GHz inter-chip wireless interconnection system，the performance of convolution codes was studied from the view of coding gain and energy consumption. The characteristics of CM7.2 channel and received signa1-to-noise ratio（SNR）were analyzed. Combining with channel coding theory，the critical distance was deduced，which was seen as the energy efficiency standard of coding system. On the basis of theoretical research，the maximum communication distance was calculated according to the coding gain which was simulated by MATLAB and the critical distance was achieved according to the circuit energy consumption which was evaluated by QuartusⅡ. Comprehensive considering the coding gain，the energy consumption and the critical distance of convolution codes，the priority coding scheme was proposed，which provided a kind of ECC technical reference for 60 GHz inter-chip wireless interconnection system and other 60 GHz short-range wireless communication systems.
