Abstract
A diversity receiver for receiving digital signals, particularly, but not exclusively, digital private mobile radio signals, comprises first and second reception branches (10,12) which frequency down convert respective input signals to the zero IF signals which are digitized and combined in a maximal ratio combiner (22) and the result is applied to a digital demodulator (23). The first and second branches are asymmetrical with the first branch (10) being fully specified and the second branch (12) being deliberately degraded relative to the first branch (10).
