Problems solved by technology

[0002] The bit synchronization of the existing adaptive equalization demodulation device is calculated by the size of the tap coefficient, and its bit synchronization has the characteristics of continuity and inheritance. When it is applied to a high-speed, bursty communication system, due to In each burst transmission, the bit synchronization signal needs to have a convergence process, and the initial phase is uncertain, and the fast bit synchronization of the communication link cannot be quickly realized, making it unsuitable for high-speed, bursty communication systems

Abstract

The invention discloses a rapid synchronization and self-adaptive balancing demodulating device based on phase selection relating to the devices of parts such as phase selection, rapid synchronization and self-adaptive balance in the communication field. The device comprises components such as a down-conversion module, a phase selection module, a self-adaptive balance module and a comprehensive output selection module. Different phase signals are output by the phase selection module; corresponding demodulating information is obtained respectively through the self-adaptive balance module; the output selection module selects corresponding demodulating information as output according to a certain rule; the self-adaptive balance is kept; rapid synchronization is realized; and the device of the invention is featured by rapid synchronization realization speed and simple realization and is especially applicable to a high speed and burst communication system.

Description

technical field [0001] The invention relates to a demodulation device for phase selection, fast synchronization, self-adaptive equalization and other parts in the communication field. Especially suitable for high-speed, bursty communication systems. Background technique [0002] The bit synchronization of the existing adaptive equalization demodulation device is calculated by the size of the tap coefficient, and its bit synchronization has the characteristics of continuity and inheritance. When it is applied to a high-speed, bursty communication system, due to During each burst transmission, the bit synchronization signal needs a convergence process, and the initial phase is uncertain, which cannot quickly realize the fast bit synchronization of the communication link, making it unsuitable for high-speed, bursty communication systems. Contents of the invention [0003] The purpose of the present invention is to avoid the shortcomings that the adaptive equalization demodul...
