HIGH-EFFICIENCY TRANSMISSION OF INFORMATION THROUGH NARROWBAND CHANNELS BASED ON ULTRA SPECTRAL MODULATION
摘要
Systems and methods for transmitting information at very high data rates through narrowband communication channels are provided. The systems and methods involve modulating a message signal with a novel non-return-to-zero, abrupt phase modulation technique and filtering the modulated signal with a sophisticated digital filter. The digital filter is designed based on a multiresolution decomposition of the frequency spectrum of the modulated signal.
