A Novel Circuit Design Based CORDIC for QAM Modulator
Xueming Wei, Shengyuan Zhou · 2007
Quadrature Amplitude Modulation (QAM) is applied extensive in the fields of broadcasting and satellite communication for its high efficiency on power consumption and bandwidth using. The paper introduces a novel circuit which makes use of CORDIC algorithm to implement QAM modulator. The CORDIC module can complete ASK function as well as export two-way orthogonal signal synchronously. By using this character, we can implement high speed QAM modulator with single filter.
