  • Orthogonal frequency division multiplexing/modulation communication system for improving ability of data transmission and method thereof
    Patent number: 7269782
    Abstract: An orthogonal frequency division multiplexing (OFDM) communication system and method for improving frequency utilization efficiency. In the system, a Reed-Solomon encoder codes input information data, and outputs a Reed-Solomon block having a second number of Reed-Solomon symbols each having a first number of Reed-Solomon symbol elements. An interleaver receives the Reed-Solomon block, and disperses the Reed-Solomon symbol elements existing in a specified one Reed-Solomon symbol within the received Reed-Solomon block in the same sub-channel positions in a fourth number of sub-channels of each of a third number of consecutive OFDM symbols.
    Type: Grant
    Filed: March 28, 2006
    Date of Patent: September 11, 2007
    Assignee: TeleCIS Wireless, Inc.
