Error Correcting Encoder Decoder

This program emulates errors occurred in data transmission at the random bit level and corrects the errors that occurred. It uses the Hamming code to encode and decode the data, ensuring reliable data transfer. Hamming code is a set of error-correction codes designed to detect and correct single-bit errors during data transmission.

Usage

1. Save the data to be encoded in the send.txt file.

2. Open the terminal or command prompt.

3. Navigate to the project directory.

4. Run the program using the following command:

   java ECED.java

5. After the application starts running, you can enter commands in the console to perform different operations:

   • To encode the data, type encode and press Enter. The Hamming encoded file will be created as encoded.txt.

   • To emulate bit-level errors, type send and press Enter. It will use the previously created encoded.txt file, emulate errors, and save it as received.txt.

   • To decode the corrupted file, type decode and press Enter. It will create a file named decoded.txt by using the previously created received.txt file.

Prerequisites

• Java 17
