Digital Transmission Over Millimeter-Wave Radio Channels: A Review [Wireless Corner]

The propagation characteristics expected to occur in a typical - thus, multipath-reflective - indoor environment are treated analytically. It is shown that the mm-wave indoor radio channel can be considered as a discrete multipath channel that might be highly frequency selective for the high symbol rates of interest (2 Gb/s). Digital transmission over mm-wave channels is discussed, including some performance-improvement methods, and the suitability of some figures-of-merit that are commonly used to quantify transmission performance.
