Estimation of noise stability of multi-frequency com.munication systems when pulse noise impacting
Abstract
Impact of impulsive noise on performance of uncoded and coded OFDM system is considered with account for the fact that the length of modulation symbol can be com.parable with average length of noise pulses. Temporal dynamics of noise is described by a Markov model. Theoretical calculations and simulation results lead to the following conclusions: efficient averaging of noise level takes place if average duration of noise pulses does not exceed 1% of OFDM symbol length; during the noise burst power losses due to impulsive nature of noise can reach 2…2,5 dB. Multi-frequency com.munication system, impulse noise, data transmission over the power line.
