Abstract
With reference to binary and quaternary, guide millimeter-wave PSK systems, the characteristics of the disturbance represented by multiple echoes, due to both mismatch reflections and mode conversions, are analysed. With regards to a link formed by many cascaded regeneration sections, realized with the same construction and installation techniques, it is shown, under rather general hypothesis, that the sum of both the thermal noise and the echoes at the output of the receiver filter, is equivalent to an additive gaussian disturbance. This allows the immediate extension to the aforesaid transmission systems of known formulae, which give the performance of the analogous echoless systems.
