Bit Error Rate Analysis for FH/MFSK System with Follower Jamming
Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 At present, methods of bit error rate (BER) analysis for frequency‐hopping (FH) system can only solve the problem of barrage jamming, but these are no comprehensive means to follower jamming (FJ). This paper proposes a method of BER analysis with FJ based on frequency hopping M‐ary frequency‐shift keying (FH/MFSK) system.
