Abstract Anti partial-band noise jamming (PBNJ) is improved by an interleaved direct sequence/frequency-hopping (IDS/FH) system based on the traditional direct sequence/frequency-hopping (DS/FH) spread spectrum method. An interleaver crossing multiple hops improves the time-frequency diversity gain. The system capacities with PBNJ are compared to a single-input multiple-output (SIMO) system with additive Gaussian white noise (AWGN) in a fading environment. An optimum IDS/FH receiver is also given. Theoretical analyses indicate that, when the PBNJ occupies 50% of the entire frequency band and the SNR is 10 dB, the IDS/FH capacity is 49% higher than that of DS/FH. Simulations show that the achievable lowest bit error rate of IDS/FH is two orders of magnitude lower than that of DS/FH with 50% PBNJ.
