ABSTRACT
Along with the technical unceasing developed, especially in the code and decoding part. At present, the code and decoding has used widely£¬Including electronic industry¡¢medicine¡¢ television media ¡¢digital signature ¡¢encryption and so on. Error-correcting code technology has been widely used. Wireless communication channel bit error will lead to a decline in the quality of transmission, affecting the normal communication. Control Channel to the BER, there are two methods: a stone increased signal transmitting power to improve the signal-to-noise ratio Channel, Another stone resolved through error-correcting codes.
This article mainly introduced the knowledge of code and the development environment of FPGA, Focused on how to use the software FPGA + PLUSII Simulation RS encoder function. Simulation and theoretical results show that what we have done [7,3,5] RS encoder and the simulation results with the theoretical results are consistent comparison.
