Abstract
The problem of optimal periodic pulse jamming design for a quadrature phase shift keying(QPSK) communication system is investigated. First a closed-form bit-error-rate (BER) of QPSK system under the jamming of pulse signal is derived. Then the asymptotic performance of the derived BER is analyzed as the signal-to-noise ratio (SNR) grows to infinity. In order to maximize the BER of the QPSK system, the optimal parameters of periodic pulse jamming signal, including the duty cycle and signal-to-jamming power ratio (SJR), are found out. Numerical results are presented to verify our analytical results and the optimality of our design.
