Combating the Distance Problem in the Millimeter Wave and Terahertz Frequency Bands.
IEEE Communications Magazine（2018）
摘要
In the millimeter-wave (30-300 GHz) and terahertz (0.1-10 THz) frequency bands, the high spreading loss and molecular absorption often limit the signal transmission distance and coverage range. In this article, four directions to tackle the crucial problem of distance limitation are investigated, namely, a distance-aware physical layer design, ultra-massive MIMO communication, reflectarrays, and i...
