摘要: New power and bandwidth efficient modulation techniques, named intersymbol interference jitter-free (IJF)-QPSK IJF-OQPSK, are presented. The properties of the IJF-QPSK IJF-OQPSK signals in linear nonlinear earth-station-satellite systems studied. A finite-state Markov chain model is used to calculate spectra hard-limited IJF-OQPSK. provides insights into spectral spreading action ideal hard-limiter on signals, Experimental, simulation, theoretical results good agreement. indicate that modulated signal exhibits much less spectrum than QPSK, OQPSK, MSK. error probability (P e ) performance IJFOQPSK an additive white Gaussian noise adjacent-channel environment evaluated. show P superior MSK narrow-band channels.
