Abstract :
An approach developed in [1] for calculating the probability of error in a direct-sequence (DS) spread-spectrum multiple-access (SSMA) system is used to study multiple-tone jamming strategies operating against direct-sequence SSMA systems. The parameters to be optimized include jammer band center frequency, number of jamming tones, and tone spacing for a fixed jammer power. Tight upper and lower bounds for the error probability in DS/SSMA systems including the degradation due to multiple-tone jammers are computed, and the tradeoff for jammer power between the single-user and multiple-user situation is studied.
