Abstract

The development of a MSK modulator/demodulator by Massey (1980) and the Hodgart and Schoones (see ibid p.211-216, 1992) implementation has prompted the development of a multi-oscillator multi-h modulator/demodulator. The approach taken has been an investigation and extension of basic CPFSK multi-oscillator modulator/demodulator design using digital logic. In this paper the multi-oscillator MSK modulator as developed by Massey is first re-examined before introducing the scheme developed by Crawford (see Master´s thesis, Dept. Elec. Eng, University of Cape Town, Rondebosch, South Africa, June, 1993). Thereafter elements of the related digital logic demodulator design are discussed
