The simulation of the system proves all the features mention above. They have designed the system using VHDL codes in Xilinx & analog filter simulation in Matlab.

In order to better and more intuitively understand the modulation and demodulation principle of multi-carry frequency shift keyying, this paper analyzes the modeling and demodulation of QPSK with the ...

In the field of modern mobile communication, (Quadrature Phase Shift Keying) QPSK modulation technology is widely used, which has a great advantage that it can work normally in a limited frequency ...

The primary goal is to recreate a given audio file after processing it through various stages of the communication model. The project covers the following key blocks: A/D converter, Encoder, Line ...
