The research of base band IJF coding and modulation technologies
Haiqiang Chen · Journal of Central China Normal University · 2004
The inter-symbol interference and time jitter free (IJF) base-band coding is researched by using the base-band pulse figuration,spectrums and phase path controlled,rolling efficient circulation filtrated technologies. A new type of IJF pulse which has fine performance,low envelope fluctuation is presented. Simulation results show that with the non-linear constant phase path, spectral spreading has been resisted and the envelope fluctuation has been reduced by using the new IJF signals on the phase modulation technologies.
