Interference immunity and energy efficiency of digital communications systems in multipath channel with fading

In the study of measures to improve channel efficiency, we developed and presented a performance analysis digital communication system for image transmission in multipath with fading, MATLAB/Simulink environment, one main advan tages being that it provides high interference immunity presence noise signal delays. The scheme has been investigated bit error rate (BER) on additive white Gaussian (AWGN) Rice Rayleigh fading operating under influence inter-symbol (hereinafter ISI) different parameters channel, where considered cases delay similar EPA (extended pedestrian model (EPA) standards). this paper, estimate effectiveness compensation distortion radio channels basis coded orthogonal frequency-division multiplexing (COFDM) technology, an adaptive equalizer, amplifiers transmitter side normalizer t he receiver side, which is acute problem field wireless communication. This can be applied transmit better quality high-resolution radiological images over network inside building analogous traffic.
