  • System and method for reliable video transmission in wireless Asynchronous Transfer Mode networks with fading
    Patent number: 6738360
    Abstract: The present invention relates to a system and method for reliably transmitting data over wireless communication channels. The invented system 10 comprises a transmitting device 12 having an error control coding circuit 20 and an interleaver circuit 22 in communication with each other. The invented system 10 also includes a receiving device 14 having an error control decoding circuit 26 and a de-interleaver circuit 28 in communication with each other. The transmitting device 12 and the receiving device 14 communicate over a wireless communication channel 16. The error control coding circuit 20 applies an error control code to the data before it is transmitted over the communication channel 16. The data is also interleaved prior to being transmitted. After transmission over the communication channel 16, the data is de-interleaved and any transmission errors are detected and corrected.

  • System and method for reliable data transmission over fading internet communication channels
    Patent number: 6601209
    Abstract: 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.
