Abstract
A multiple phase PSK demodulator for use in a spread spectrum communication system includes a plurality of baseband frequency converters coupled to a corresponding plurality of differential decoders in order to directly recover the encoded PSK data. The logic outputs of the plurality of differential data decoders are coupled to a majority vote logic circuit for determining the correct logic level output signal of the plurality of differential data decoders. In another embodiment, a three phase resistive network is used to convert the two phase quadrature output of two baseband frequency converters to plural phase outputs coupled to the inputs of a corresponding plurality of differential data decoders.
