摘要:

提出了一种支持60 GHz毫米波通信波束赋形机制的码本设计方法. 为满足低功耗需求,码本设计仅进行相位移动而未作幅度调整,其中码本矩阵采用相位间隔相同、幅度为1的N个复数权值构建. 仿真结果证实,与IEEE 802153c码本设计相比,高阶相位码本可获得相似的波束主瓣形状,同时波束将具有更低的旁瓣电平和更高的主瓣增益. 该码本方案可在多用户环境下显著抑制空间干扰,提高网络累计信道容量,且对相位误差产生的波束偏移同样具有稳健性.

Abstract:

A method for codebook design is proposed to support beamforming mechanism in a 60 GHz millimeter-wave wireless communication environment. The codebook is designed with only phase shifting but not any amplitude adjustment to meet the low power consumption requirement. N complex numbers of the same phase interval and amplitude of 1 are designed to generate a codebook matrix. Simulation shows that, compared with the codebook in IEEE802.15.3c, a similar mainlobe patterns can be obtained in the proposed high-order codebook, while the sidelobe level appears lower, and the antenna gain at the direction of main response axis is higher. Meanwhile the interference decreases obviously with an improved total channel capacity in the practice environment, and the codebook is also robust to the beam shifting deriving from phase errors.

Key words: 60 GHz wireless communication, beamforming, codebook design
