Error Detection and Correction for a Multiple Frequency Quaternary Phase Shift Keyed Signal

Abstract

A multiple frequency quaternary phased shift (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. Keywords: Acoustic communications; Computer communications; Ship-to-ship shore communication.
