  • Orthogonal frequency division multiplexing transmitter system and VLSI implementation thereof
    Patent number: 7379417
    Abstract: A system for transmitting data in wireless communication employing an improved orthogonal frequency division multiplexing (OFDM) transmitter is devised. The orthogonal frequency division multiplexing (OFDM) transmitter is improved for VLSI implementation. The improved orthogonal frequency division multiplexing transmitter is configured to provide multi-rate support, low latency, reduction in the turnaround time and reduction in the gate count during data transmission.
    Type: Grant
    Filed: February 19, 2003
    Date of Patent: May 27, 2008
    Assignee: Wipro Limited
    Inventors: Shyam Ratan Agrawalla, Aseem Pandey, Shrikant Manivannan
