A multiple frequency quaternary phased shift keyed (MFQPSK) signaling system has been developed and experimentally tested in a controlled environment. In order to insure that the quality of the received signal is such that information recovery is possible, error detection; correction (EDC) must be used. This thesis reviews various EDC coding schemes available and analyzes their application to the MFQPSK signal system. Hamming. Golay, Bose-Chaudhuri-Hocquenghem (BCH), Reed-Solomon (R-S) block codes as well as convolutional codes are presented and analyzed in the context of specific MFQPSK system parameters. A computer program was developed in order to compute bit error probabilities as a function of signal-to-noise ratio. Results demonstrate that various EDC schemes are suitable for the MFQPSK signal structure, and that significant performance improvements are possible with the use of certain error correction codes.
