Abstract :
This paper is concerned about the demapping method using the pilots inserted in transmitter in COFDM (coded orthogonal frequency division multiplexing) system which is the standard transmission system of terrestrial digital TV in Europe. We have tested the demapping method of this paper under the standard Rayleigh and Rician fading channel and obtained better performance than conventional soft decision demapper
