WebSpace diversity has the disadvantage of requiring significant antenna separation, at least in the VHF and lower UHF bands. In the case where multipath signals arrive from all directions, antenna spacing on the order of 0.5λ to 0.8 λ is adequate in order to have reasonably independent, or decorrelated, channels. WebIn telecommunications, maximum-ratio combining (MRC) is a method of diversity combining in which: . the signals from each channel are added together,; the gain of each channel is made proportional to the rms signal level and inversely proportional to the mean square noise level in that channel.; different proportionality constants are used for each channel. …
