IN-PHASE SIGNAL AND QUADRATURE SIGNAL GENERATOR OF MULTI-PORT NETWORK AND METHOD THEREOF

摘要

PURPOSE: An in-phase signal and a quadrature signal generator of a multi-port network and a method thereof are provided to reproduce an I/Q signal having exact coordinate and magnitude by repeatedly adjusting an initial parameter and magnitude according to a preset standard criterion. CONSTITUTION: A multiport network part(110) changes a received signal into a plurality of phase signals having different phases according to a preset reference signal. A signal regenerator(120) restores the original data based on the power of the phase signals from the multiport network part. A controller(130) repetitively controls the restore operation of the regenerator. The original data restored from the signal regenerator satisfies the preset criterion range.
