Abstract：In this paper, we design codebooks for supporting beamforming in 60 GHz frequency band. The proposed codebooks support both discrete and continuous phase resolution, respectively. The codebooks with discrete resolution were derived following the concept initiated by TG3c in IEEE 802.15.3c standard while the codebook with continuous resolution is based on Kaiser-Bessel windowing function. The designed codebooks give weight vectors that have reasonable level of side lobe and can be used in 60 GHz systems employing analog and digital phase shifters. The codebooks were created by considering the main features of linear array such as array gain, side lobe level, directivity loss and half-power beamwidth of the radiation pattern. The simulation results show that the weight vectors of the designed codebooks improve the performance of linear arrays in terms of power of side lobe, directivity loss, and output SNR of beamforming receiver. The designed weight vectors are frequency independent; in this case, they are both applicable in wideband and narrowband beamforming systems.

摘要：本文提出了一种支持60GHz频段波束成形的码本. 设计的码本支持离散和连续相位精度.离散精度的码本基于TG3c提出的IEEE 802.15.3c标准中的码本权重概念，而连续精度的凯塞贝塞尔窗函数。设计的码本的权重矢量可以得到合理的旁瓣等级并且可用于采用模拟和数字相位偏移的60GHz系统。提出的码本考虑了线性阵列的主要特性，如阵列增益、旁瓣等级、定向损耗和辐射图的半功率带宽。仿真结果表明设计的码本的权重矢量改进了线性阵列在旁瓣功率、定向损耗和波束形成接收机的输出信噪比。设计的权重矢量与频率无关，所以设计的码本可以应用到宽带和窄带波束形成系统中。
