The Impact of Signal Bandwidth on Indoor Wireless Systems in Dense Multipath Environments
... Maximal ratio combining and equal gain combining both use more than one path in two distinct ways. In maximal ratio combining each branch signal is weighted (by ak) in proportion to its ... the time being. In general there are three methods for processing these signals. Known as linear combiners they are selection diversity, maximal ratio combining, and equal gain combining. Under ... co-phasing of the signals. Conversely, equal gain combining does not weight each signal before combining (all ak = 1). In general, maximal ratio combining provides the best performance gain,...
