Abstract :
Baseband pulse shaping is proposed to improve the performance of M-ary frequency shift keying (FSK) with limiter discriminator detection in a satellite mobile channel. Numerical results obtained for binary, quaternary and octonary signals, indicate that pulse shaped signals perform significantly better than FSK signals. The error rate floor in presence of a Doppler shift is also analyzed. Numerical results indicate that the error rate floor of the pulse shaped signals is significantly lower than that of FSK signals.<>
