Abstract

An EBPSK-based communication method and system are disclosed in the present invention, relating to the field of digital communications. The method includes: a transmitting end performs encoding and EBPSK modulation for an information sequence to obtain an EBPSK modulation signal; and a receiving end performs EBPSK demodulation and decoding for the EBPSK modulation signal to obtain the information sequence. The present invention can enhance the anti-interference ability of the EBPSK communication system.

Description

technical field [0001] The present invention relates to a digital communication system, in particular to a transmitter for extended binary phase shift keying (Extended Binary Phase Shift Keying, EBPSK) coded modulation communication and a corresponding fast bit synchronization and demodulation decoding method, belonging to information in digital communication field of modulation and demodulation. Background technique [0002] 1. EBPSK modulation [0003] In a digital communication system, the process of moving the baseband signal representing the transmitted data to the required transmission frequency band is called modulation, and vice versa is called demodulation. For binary digital modulation, a certain parameter of the sinusoidal carrier in the symbol period, such as amplitude, frequency or phase, can be changed correspondingly through binary data symbols "0" and "1", and the corresponding amplitude keying (2ASK), frequency Shift keying (2FSK) and phase shift keying (2...
