Abstract:

ING CODES, CONVOLUTIONAL CODES, DATA TRANSMISSION SYSTEMS, ERROR CORRECTION CODESThe report contains the details and results of a study of the susceptibility of a binary noncoherent frequency shift keying NCFSK detection system to various types of jamming signals. Probability-of-error expressions are derived for two types of jamming signals CW and linear FM, serving as a beginning to a more complete theoretical susceptibility analysis. The manthematical model and the procedures used provide a basis for additional derivations involving non-Gaussian interference. Seven possible error-corr ction schemes are investigated and compared on the basis of 1 tolerable binary symbol error rates for a given character error probability, and 2 the interference power levels associated with these error rates. System complexity is considered qualitatively. Recommendations are made concerning additional studies and system modifications. Author
