A non-redundant differential MSK demodulator with double-error correction capability includes a differential detection stage, an error signal generator stage, and an error detection-and-correction stage. Differential detectors receive modulated MSK input. The error signal generator converts outputs from the differential detectors into orthogonal error signals. The error detection-and-correction stage compares an algebraic sum of the error signals to a threshold value and outputs a correction value based thereon. The correction value is added to output from the differential detection stage to produce demodulated MSK output.
