针对紧凑空间互耦效应影响下的大规模数字相控阵混合ADC接收机性能评估问题,提出一种混合ADC接收机性能分析方法。首先,通过联合考虑三维信道模型、互耦效应模型和ADC量化噪声模型,对互耦效应影响下的传播信道进行建模;然后,采用线性最大比合并接收机,基于随机矩阵理论,推导给定天线阵列拓扑结构下系统可达速率的闭式表达式;最后,分别对均匀线性阵列、均匀平面阵列在不同混合ADC配置方案下的可达速率进行理论计算和数值仿真。计算与仿真结果均表明优化混合ADC配置方案可以有效提升系统可达速率,该结论可以为紧凑空间下高可达速率的混合ADC接收机设计提供理论支撑。
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 numerically simulated. The calculation and simulation results both indicated that optimizing the mixed-ADC configuration scheme could effectively 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.
