Abstract :
The mPSK interference suppression in the DSSS/QPSK system is investigated. For this purpose we propose a new structure, called ξ-structure. Bit error probability versus interference bit interval duration, as well the probability versus interference-to-signal ratio in the presence of mPSK interference is evaluated when an adequate scheme for its suppression is implemented. It is shown that this scheme is good for both narrowband and wideband interference suppression
