Performance of BPSK/BPSK and OQPSK/BPSK spread spectrum communication systems in the presence of multiple-tone jammer

Abstract

It is known that OQPSK has the same theoretical bit error performance as BPSK and QPSK, since QPSK and OQPSK are configured as two BPSK signals modulating orthogonal components of the carrier.The error probability of BPSK/BPSK and OQPSK/BPSK direct sequence spread spectrum communication systems, in the presence of the multiple tone jammer, is developed using a simple technique. This technique clearly, illustrates the same error probability between the OQPSK/BPSK and BP SK/ B PS K systems.
