Abstract :
This article deals with the implementation in hardware and the study of performance of a modem using trellis-coded PSK modulation with a signalling rate of 9.6 kbit.s in the Ka-band. The modems thus designed are used to simulate the transmission of data through a hardware channel simulator with attenuation in the band-pass mode. This can simulate either a Rayleigh channel, a Rician channel or a Loo (1985) channel with lognormal masking and Rayleigh fading. The results are presented in terms of error rate as a function of signal/noise ratio
