A digital wired / wireless communication system that uses a digital filter to equalize group delay

摘要

1. The technical field to which the invention described in the claims belongs;Digital wired / wireless communication system.;2. Technical challenges to be solved by the invention;An apparatus for equalizing group delay using a digital filter and adjusting a tap coefficient of a digital filter is provided.;3. The point of the solution of the invention;The present invention uses a digital filter at a baseband stage in a modulation section of a digital communication system and adjusts a coefficient of the digital filter by inversely calculating a group delay occurring in an RF channel filter when sharpening a pulse signal, To equalize.;4. Important Uses of the Invention;Digital wired / wireless communication system, phase communication system.
