System and method for reliable data transmission over fading internet communication channels

摘要

The present invention relates to a system and method for reliably transmitting Internet Protocol (IP) data packets over fading Internet communication channels. The invented system 10 comprises a transmitting device 12 having an interleaver circuit 22. The invented system 10 also includes a receiving device 14 having a de-interleaver circuit 38. The transmitting device 12 and the receiving device 14 communicate over a fading Internet communication channel 16. The transmitting device 12 applies error control coding to the IP packets before they are transmitted over the fading Internet communication channel 16. The Interleaver circuit 22 interleaves the IP data packets before transmitting them over the fading Internet channel 16. The receiving device 14 receives the interleaved IP packets from the fading Internet channel 16. The de-interleaver circuit 38 de-interleaves the received IP data packets. The receiving device 14 also uses the error control coding to detect and correct any errors incurred during transmission. The interleaving "spreads out" transmission errors over several IP packets and thus makes the error control and correction process more effective and efficient.
