Design of the Interweave Encoder Based on FPGA

A design of interweave encoder based on FPGA is introduced. The Interweave Encoder Principle is described and the design simulation result is presented. It has been known that the information-bearing signal generated at the transmitter may inevitably be interpreted mistake at the receiver due to distortion of the signal in the channel between the transmitter and receiver. Therefore forward error correction is often used in digital communication system to correct the error codes generated at the transmitter. The digital communication system which adopt error correction encoding and interweave encoding can correct random errors and disposal paroxysmal errors, consequently, improve communication quality. By all appearances, advanced techniques, development tools and high performance FPGA devices, may not only accelerate the process of project, but also boost up the reliability and versatility of hardware, as well as the convenience of design upgrade.
