This project aim was to build wireless software modem for data communication between two computers using an acoustic interface in the voice frequency range (20Hz– 20,000Hz). The transmitting antenna is a speaker (frequency response of: 90Hz – 2

国外的详细的OFDM设计过程文档，对学习OFDM非常有帮助，并且有仿真结果。-This report discusses the design and implementation of an OFDM modem for a simplex communication between two PCs over a frequency selective channel. First a brief introduction is provided by explaining the b

有QPSK的调制解调，信噪比，信道等，使用matlab代码编写和绘图-There QPSK modulation and demodulation, signal to noise ratio, channel, etc., using matlab code writing and drawing

This project is simulation of the MASK modulation in the MATLAB. this project has one file for Modulating some random number and one file for demodulating of the signal. just run the first code and after that run the second code. this code also has
