Abstract
A system for diversity processing two signals transmitted and/or received via two diversity antennas includes at least four respective propagation paths coupling the signals to the two diversity antennas. Diversity processing is primarily in the form of decorrelation achieved by means of time variable delay elements that apply time variable delays to the signals propagating over at least two of the propagation paths in the system. The related processing may take place either at RF or IF, or at baseband, whereby the time variable delays are applied by subjecting the baseband signals to multiplication by a complex signal.
