Robustness of OFDM signal against temporally localized impulsive noise

摘要

We present the theoretical analysis of the bit error rate (BER) performance of single-carrier modulation (SCM) and orthogonal frequency division multiplexing (OFDM) systems under two types of temporally localized impulsive noise environments, namely stationary and bursty impulsive noise. The robustness of OFDM system against impulsive noise is then discussed and compared with that of the SCM system at the same transmission rate. In addition to the common knowledge on OFDM, we show that OFDM system is sometime less robust to impulsive noise than SCM system.
