Influence of channel amplitude characteristic nonlinearity in system with OFDM
In the article analysed influence transient noise, which depend on nonlinearity amplitude behavior of channel, on noise-immunity receiving signal at OFDM systems. To this effect they detect power spectrum of group signals on the out of nonlinearity track. They had calculated expressions signal coupling noise ratio for separate subcarrier. The probability of errors was calculated in correlation reception D-QPSK signals subject to fluctuating and transient noises.
