摘要：
A receiver for a space diversity radio transmission system, the receiver including a diversity combiner (CD) and a diversity control circuit (7) which is responsive, inter alia, to a distortion value (F). If the receiver includes a self-adaptive equalizer (6) in the transmission path of the composite output, the control circuit may calculate the distortion value from the coefficients (ai, bi) used to control the filter portion (EG) of the equalizer. If the combiner is also responsive to an insufficient power value (G), the distortion value may be added to the insufficient power value in order to obtain a single control magnitude (8) which is used for controlling the diversity combiner in a manner that avoids any abrupt transition between the low power mode and the low distortion mode.
