Several fractionally spaced equalizers(FSE) which could be used in 60 GHz systems are presented in this paper. For 60 GHz systems, low-power equalization algorithms are favorable. We focus on FSE in both time domain(TD) and frequency domain(FD) in order to meet different complexity requirements of 60 GHz systems. Compared with symbol spaced equalizer(SSE), FSE can relax the requirement of sampling synchronization hardware significantly. Extensive simulation results show that our equalization algorithms not only eliminate ISI efficiently, but are also robust to timing synchronization errors.

Millimeter-wave communication has received considerable attention for use in new-generation broadband wireless communication because of the scarcity of microwave band spectrum resources. The unlicensed frequency band at 60 GHz is suitable for indoor short-range broadband communication. In this paper, we introduce a 60 GHz millimeter-wave short-range wireless communication demo system adhering to the IEEE 802.11 ad standard and targeting high-definition video streaming transmission. The system uses single-carrier transmission with frequency-domain equalization. The hardware prototype consists of a 65-nm CMOS radio-frequency front-end and a baseband transceiver for the physical layer functions. Important baseband technologies such as carrier synchronization, phase noise compensation, frequency-domain equalization, and low-density parity-check decoding based on probability calculation are also discussed. The system performance is demonstrated in an experiment on high-definition video transmission, where a data rate of 3.52 Gbps is achieved with a quadrature phase-shift keying signal over a distance of 5.109 m.

为了准确评估1bit脉冲超宽带接收机存在采样抖动时的性能,提出了一种基于中心极限定理的性能分析方法.首先将存在抖动的采样信号通过一阶泰勒展开为无抖动采样信号和采样抖动变量的线性函数,然后利用中心极限定理将接收机的判决变量建模为一个高斯分布的随机变量,从而得出接收机误码率表达式,最后根据采样抖动的随机分布模型,给出平均误码率上界表达式.该分析方法首次给出存在采样抖动时1bit数字接收机性能的解析表达式,并且可用于其他线性干扰存在情况下的性能评估.实验结果表明,给出的平均误码率上界可以很好地反映接收机的实际性能,并且可用于高斯分布和平均分布两种随机采样抖动模型.
