Abstract
A system for MPSK symbol hypothesis testing. A received symbol having in-phase (I) and quadrature (Q) components is input to the system. Multipliers for each of the components are determined corresponding to the MPSK symbol hypothesis s being tested. The symbol s is a quadrature symbol having in-phase and quadrature components, sand s, respectively. The multipliers are each derived from fractions which approximate to a desired level of resolution either ±sor ±s. The system multiplies the I and Q components by their respective multipliers through a discrete series of add, shift, and twos complement operations. It then derives a metric for testing the hypothesis from the resulting products.
