Abstract

A novel form of equal gain diversity combiner based upon FFSR signal processing has been investigated in conjunction with a TTIB-SSB system at 457 MHz. Initial results with a two-branch combiner show that a significant improvement in channel quality can be realised with both speech and data communications in fading low signal strength conditions. An attractive feature of the combiner is that the individual branches are co-phased automatically to a reference local oscillator operating at audio frequencies. Moreover, the combiner could be simply integrated into a chip set but does require almost two complete receivers for the two-branch system. The increased complexity and cost of the combiner may be justified in some applications. At present SSB/FFSR systems are being used or actively considered for private mobile radio, large cell mobile radio, mobile-satellite and airphone communications
