PSK Demodulation Program

This C++ program performs Phase Shift Keying (PSK) demodulation on binary data stored in a file. It takes command-line arguments to configure the modulation order, preamble, and input file.

Features

• Modulation Order: Configurable PSK modulation order.
• Preamble Handling: Uses a binary string for preamble.
• File Input: Reads binary data from a file and processes it.

Requirements

• C++ Compiler: g++ 14.2.0 or later
• Standard Library: C++20

Compilation

To compile the program, use the following command:

g++ main.cpp -o main -std=c++20

Usage

Run the program using the following syntax:

./main <mod_order> <preamble_binary> <filename>

Parameters

<mod_order>: The modulation order (e.g., 4 for QPSK).
<preamble_binary>: A binary string representing the preamble (e.g., 01011110).
<filename>: The path to the binary file containing the input data (e.g., ./data.bin).

Example

To run the program with modulation order 4, a preamble of 01011110, and an input file named data.bin, use the following command:

./main 4 01011110 ./data.bin
