Based on the anti-fading communication of the TFSK(time frequency shift keying),a new method of using random bits to realize pseudo noise-TFSK with multi-PN code,multi-frequency and multi-time slot is proposed by applying noise coding technology into TFSK,so the anti-jamming(AJ)and low probability of intercept/detection(LPI/D) performance of the pseudo noise TFSK signal is improved remarkably.
