Complex Optimization of Signal Frequency Distortion in Communication Channels with OFDM

Abstract

A mathematical model of channels with incoherent bit reception of the distorted signals with OFDM is offered. The choice of a complex indicator is proved for the degree account of frequency distortions of signals in channels with the linear phase-frequency characteristic and non-uniform amplitude-frequency characteristic. The optimization problem solution of partial compensation of signals phase distortions is presented by adjusting the amplitudes of the harmonic components of the signal spectrum. An example of energy control realization of a signal spectrum is considered in the power amplifier of the transmitting device with compensation of phase distortions.
