Gardner Brian R: Radio communications link with diversity. Racal Res, May 8, 1991: GB2237706-A (98 worldwide citation)

A base station 10 has two transmitting antennas 20, 22 which both transmit the same signal to a mobile station 12, the signal via antenna 22 being delayed by a time delay unit 24 to ensure de-correlation between the transmitted signals. It is unlikely that multi-path fading will occur simultaneously ...
