ABSTRACT:
A signal combiner for use in a space diversity radio receiving system. The signal combiner accepts two signals which have been received at physically diverse locations and which have been converted from radio frequency to intermediate frequency. Each of the signals is checked for signal strength and for amplitude versus frequency dispersion. Each signal is run through a separate amplitude slope equalizer which removes amplitude slope. Each signal is then run through a separate squelch circuit which either attenuates the signal, or passes it on undiminished. The squelch circuits are controlled by a control circuit which selectively activates one or neither of the squelch circuits based on the difference in signal strength between the two received signals and the signal dispersion of each of the signals. The outputs of the squelching circuits are then combined to create a composite signal which is comprised of one or both of the equalized signals.
