Hamming Code for Error Detection and Correction using VHDL

Hamming code for error detection and correction methodology is used for error free communication in communication systems. In communication system information data is transferred from source to destination through channel. In between, source and destination, data may be corrupted due to any type of noise. To find original information we use Hamming code error detection and correction technique. In hamming code error detection and correction technique, to get error free data at destination, we encrypt information data according to even and odd parity method before transmission of information at source end. In this project 14 bit Information data is divided into two groups of 7bit data. After this division each group is encrypted using four Redundancy bit. In this way 14bit information data at sender end is now converted into two groups of 11bit data (with redundant bits). Both groups are joined to make total 22 bit Information data. At Receiver end 22 bit information data in divided into two groups of 11 bit data and each group is detected and corrected using even and odd parity check method. After correction both group are joined together to Receive 22bit original information data. Here, Xilinx ISE 10.1 Simulator has been used for simulating VHDL Code. Xilinx ISE 10.1 S is a simulator which is used for simulating HDL language and schematic circuit diagram. Here we have used Xilinx simulator to simulate VHDL code for transmitter and receiver
