Abstract :
A new interference suppression method namely the polar exciser (PE) is proposed. We have simulated the BER performance of a direct sequence (DS) system with PE interference suppressor added in an environment where a strong broadband constant envelope interference perturbs the desired DS signal detection. Interference scenarios included are constant envelope BPSK, constant envelope FSK and sweeping interference
