AbstmctThe closed form expression of the probability density function of the disturbance due to a Quaternary PSK (QPSK) cochannel interferer is obtained. Then the bit error rate performance of QPSK in the presence of multiple cochannel interferers and additive white Gaussian noise (AWGN) is analyzed. In particular, a closed form expression is given to evaluate the bit error probability of QPSK with multiple cochannel interference. It is shown that in order to determine the minimum signal-t… CONTINUE READING
