我们建议使用能量检测的单流传输和接收的一个非常大的数量的天线，主要应用于毫米波通信。应用能量检测的原因是低复杂度、成本和功率效率。虽然能量检测和毫米波通信分别由于噪声敏感性和传播衰减而被限制在短距离，但是通过大量接收天线进行的处理克服了这些缺点，以提供显著的范围扩展。该处理仅基于信道和噪声的长期统计，使其对用户移动性和不完善的信道知识具有鲁棒性。
We propose the use of energy detection for single stream transmission and reception by a very large number of antennas, with primary application to millimeter wave communications. The reason for applying energy detection is low complexity, cost and power efficiency. While both energy detection and millimeter wave communications are limited to short ranges due respectively to noise sensitivity and propagation attenuation, processing by a large number of receive antennas overcomes those shortcomings to provide significant reach extension. This processing is solely based on long-term statistics of the channel and noise, making it robust to user mobility and imperfect channel knowledge.
