FPGA-based experimental board for error control codes

This paper proposed an experimental device that emulates and facilitates teaching the theoretical concepts of error-control coding (ECC) techniques. Two prototypes laboratory boards were designed implemented. The first board simulates transmitter side a typical digital communication system. It mainly contains data source, (7,4) Hamming encoder, cyclic redundancy check encoder (CRC), Gaussian noise generator. second has two types decoders, syndrome decoder, maximum likelihood (ML) decoder accepts received soft signals at channel output. Each several control switches so trainee can change code variables, power, user ID, in addition to display tools such as light-emitting diodes (LEDs), test points for oscilloscope help observe results. Moreover, results setting variables also be displayed on PC’s screen connected through USB port organic light emitting (OLED) is attached receiver board. pipelining architecture field programmable gate array (FPGA) was exploited this system reduce processing delay hence increase throughput. Furthermore, we proved both tests are identical.
