Performance Analysis of Large-Scale Digital Phased Array Mixed-ADC Receiver in Compact Space
摘要
Abstract
In order to evaluate the performance of large-scale digital phased array mixed-ADC receivers under the influence of mutual coupling effects in compact spaces,a performance analysis method was proposed.Firstly,the propagation channel under the influence of mutual coupling effects was modeled by jointly considering the three-dimensional channel model,mutual coupling effect model,and ADC quantization noise model.Then,used a linear maximum ratio combining receiver and based on random matrix theory,a closed form expression for the achievable rate of the system under a given antenna array topology was derived.Finally,the achievable rates of uniform linear arrays and uniform planar arrays under different mixed-ADC configurations were theoretically calculated and numeri-cally simulated.The calculation and simulation results both indicated that optimizing the mixed-ADC configuration scheme could effec-tively improve the system achievable rate,and the conclusion could provide theoretical support for the design of high achievable rate mixed-ADC receivers in compact spaces.关键词
