Suppressing Intentional Electromagnetic Interference (IEMI) in Wireless Communication System Using Complex Signal Spectrum Shifting Technique

It is well known that (non)intentional electromagnetic interference (IEMI) can cause the performance degradation and the rise of bit error rate (BER) of wireless communication system. This paper presents the study on suppressing intentional electromagnetic interference in communication system using complex signal spectrum shifting technique. The anti-IEMI techniques are at first introduced, and further, modeling process and simulated results of bit error rate (BER) are given for different signal to noise ratio (SNR) and signal to interference ratio (SIR).
