R. Verdone, JOINT EVALUATION OF TIME AND FREQUENCY-SELECTIVE FADING EFFECTS IN CPM SYSTEMS WITH LDI DETECTION, European transactions on telecommunications and related technologies, 6(2), 1995, pp. 181-186
Limiter - discriminator integrator (LDI) detection of binary full and
partial response continuous-phase modulation (CPM) in a channel charac
terised by Rayleigh fading, time and frequency selectivity, is investi
gated. An analytical approach able to take into account the presence o
f any number of delayed paths in the channel is presented. The narrowb
and bandpass filter effects and the role of the post-detection integra
tion time and other system parameters are evaluated. The numerical,res
ults show that full-response schemes perform better than partial-respo
nse modulation formats as regards the error floor due to the Doppler e
ffect or the presence of a delayed version of the received signal.
