Performance Analysis of Anti-narrowband Noise Interference of Phase-Inversion Symmetric Method in Time-Domain

摘要

The principle of Phase-Inversion Symmetric method (PISM ) in time-domain based on noise correlation is presented, and its anti-narrowband noise interference ability is analyzed. The simulation models of PISM in time-domain and narrowband noise interference are designed. The band-limited Gaussian white noise and narrowband noise interference model is applied to PISM in time-domain to study anti-interference ability of this method. Simulation results show that the bit error rate (BER) of PISM in time-domain in band-limited Gaussian white channel is close to zero, and the bit error rate of this method in narrowband noise interference is very low, and prove the Phase-Inversion Symmetric method in time-domain has good ability against narrowband noise interference.
