Implementation of Luby Transform Error Correcting Codes on FPGA

Luby Transform (LT) codes are rate less codes which are a type of fountain codes. They provide good performance over other fountain codes because, more efficient encoding and decoding algorithms can be devised for this code. These codes are rate less codes because they allow for flexible and adaptive rate allocation during the encoding process. With this, any desired code rate can be achieved by controlling the number of parity symbols generated during the encoding process. This paper explains the encoding and decoding aspects of LT codes in detail and generation and decoding is performed using MATLAB. Hardware implementation of LT code is attempted on FPGA by using Verilog code. As it is shown, the codes are very simple to implement and can be used as a more powerful error correcting codes.
