We present a high‐fidelity measurement‐based nonlinear model of low‐complexity millimeter‐wave transmit and receive circuits for design and analysis of 1‐bit on‐off‐key (OOK) massive MIMO wireless communications systems. The receive model is based upon a fabricated 38 GHz energy detector, representative of state‐of‐the‐art OOK millimeter‐wave receivers. The model is validated with measurements and includes nonlinear noise modeling. Performance of a large‐scale massive MIMO system is predicted with the model, and predictions are compared against a 4‐transmit‐element, N‐receive‐element testbed. Finally, we compute the channel capacity of several OOK massive MIMO systems, exploring tradeoffs in power consumption and number of transmit and receive cells. Results indicate a 1‐bit OOK array with low power pre‐amplifiers can achieve similar capacity to a classical linear receiver with less than one tenth the power consumption. The 1‐bit array compensates for the per‐cell simplicity by increasing the total number of cells while maintaining low overall power consumption.

适用于大规模MIMO无线通信系统的低分辨率毫米波收发器的高效建模

我们为低位复杂度毫米波发射和接收电路提供了一种基于高保真度测量的非线性模型，用于设计和分析1位开关键（OOK）大规模MIMO无线通信系统。接收模型基于预制的38 GHz能量检测器，代表了最先进的OOK毫米波接收器。该模型已通过测量验证，并包括非线性噪声建模。该模型可预测大规模大规模MIMO系统的性能，并将预测结果与4个发射元素，N个接收元素的测试台进行比较。最后，我们计算了几个OOK大规模MIMO系统的信道容量，探讨了功耗以及发射和接收小区数量之间的权衡。结果表明，具有低功率前置放大器的1位OOK阵列可以达到与传统线性接收器类似的容量，而功耗却不到其十分之一。1位阵列通过增加单元总数，同时保持较低的总功耗来补偿每单元的简单性。
