Diversity reception for error-rate reduction in mobile-radio data links
John David Parsons, A. Pongsupaht · Electronics Letters · 1979
A dual predetection diversity combiner based on the double-heterodyne principle has been constructed for use in the v.h.f. mobile-radio band. Tests using fading simulators have demonstrated its effectiveness as a combiner, and shown that it provides a substantial improvement in b.e.r. when used in an f.s.k. data receiver.
