Design and Implementation of a -QAMModulatorAmplitudeQuadratureDigital using FPGA

In this paper, we propose the design and implementation mechanism for different digital modulators such as Synthesizer Frequency Digital Direct Quadrature based on the use of odulators m 64 -QAM Amplitude Quadrature (QDDFS) using Cyclone II EP2C20F484C7 FPGA from ALTERA placed on education and development board DE-1 with the following parameters: .=50MHz CLK : F Clock frequency --Modulation type of signal is : QAM-64 .-Frequency range : (0.011 Hz10 MHz) .-Frequency Resolution : (0.011 Hz) .-Signal amplitude(5V) .-Data frequency : 1KHz .-Digital designs allow the slides to modify and design development for results and better through reprogramming, depending on the user's desire.
