“…At the same time, Garrison showed that the power spectra of digital FM could be calculated by making linear approximations to the input waveforms [26]. Late in 1976, Anderson and deBuda showed that continuous phase or frequency shift keying systems displayed a trellis structure and could be detected using the Viterbi Algorithr2].…”

Tentative conclusions from this study indicate that spread spectrum multi-h modulation is a viable technique for low probability of intercept applications. New methods for the application of continuous phase modulation indices have been derived and the impact of the spreading sequence on performance has been revealed. Realistic numerical evaluations with correlated noise samples indicate enhanced performance and reduced probability of detection when compared to DS/BPSK. Spectral control is obtained along with power efficiency to allow detection at lower signal-to-no:se ratios. _ 2iA,(8.23) Qj ~I E 1cos(2irhj)j COS(0(0)) _ i~n(2,rhj,) sin (V(0)) 1 cos(0(0)) Q2 laj~j=-I,hjj sin(0(0))

Among the many bandwidth efficient constant envelope modulation schemes that fall in the class of continuous phase frequency modulations, minimum‐shift‐keying is undoubtedly the most popular of the group that transmit binary information. The reason for this stems perhaps from the fact that MSK can be viewed both from the standpoint of frequency modulation and pulse‐shaped offset quadrature phase‐shift‐keying thereby allowing a large degree of flexibility in the design of transmitter and receiver implementations. In this chapter we explore a large variety of these implementation options with emphasis on their analytical characterization as well as their power and bandwidth performance behaviors. While the chapter attempts to cover a large body of the published literature on MSK, it is not offered to the readership as an all‐inclusive treatise on the subject but rather one that highlights the key technical contributions that are essential to a basic understanding of the modulation method as well as its associated demodulation, detection, and synchronization techniques.
