A research on an error control coding method in complicated channel

This essay mainly discusses ways of modulation and channel coding under the circumstance of coastal sophisticated channel. According to the feature of actual channel, it provides a way of coding which fits error controlled coding. Via CRC checkout coding, FEC appended error correction and other ways, it improves the function of anti-jamming and error coding, which excellently boosts the frequency utilization of the system, and also provides a new thought for high-speed data transmission in the existing narrowband devices.
