This repository contains Verilog code for an OFDM (Orthogonal Frequency Division Multiplexing) modulator designed using FPGA (Field Programmable Gate Array) hardware description language.
OFDM is a widely used modulation technique in modern communication systems, particularly in wireless networks such as Wi-Fi, LTE, and digital television. This modulator is designed to take input data and perform the following steps:
- QAM Mapping: Maps input data bits to symbols in a QAM (Quadrature Amplitude Modulation) constellation.
- IFFT (Inverse Fast Fourier Transform): Converts the QAM symbols into time-domain signals using an IFFT operation.
The design is parameterized to allow customization of input and output data widths, QAM constellation sizes, and other parameters, providing flexibility for various applications.
To use this modulator in your project:
- Clone this repository to your local machine.
- Customize the parameters in the Verilog modules (
module_name.v) as needed for your application. - Instantiate the modulator modules in your design and connect them according to your system requirements.
- Simulate the design using the provided testbench in the
modulator_tb.svfile to verify functionality. - Synthesize the design using your FPGA synthesis toolchain and program it onto your target FPGA board.
Contributions to improve this OFDM modulator design are welcome! If you find any issues or have suggestions for enhancements, please open an issue or create a pull request.
