摘要

A radio receiver is provided comprising first (10) and second (11) antennas, physically spaced apart to provide diversity and an equalizer (20) for combining components of a received symbol which are separated in time. The signals received at the first and second antennas are combined in a combiner (19) and coupled to the equalizer. Delay means (18) are provided in the receive path of one of the antennas, for delaying signals received at that antenna with respect to signals received at the other antenna whereby the probability of destructive interference between the signals from the first and second antennas is significantly reduced. in accordance with a second aspect of the invention, a similar arrangement is provided for diversity in transmission.
