  • Patent number: 7961697
    Abstract: The present invention relates to a method for estimating a timing error and a frequency offset in a high-speed portable Internet system and a method thereof. A predetermined preamble symbol is added to an OFDM frame to be transmitted by a transmitter according to an exemplary embodiment of the present invention, an IFFT operation is performed, and then a pseudo noise is multiplexed by the preamble symbol to estimate the timing error and the frequency offset. A receiver receives an OFDM symbol, extracts the preamble symbol from the OFDM symbol, and multiplexes the extracted preamble symbol by a local pseudo noise, which is equal to the pseudo noise used by the transmitter but is shifted.

  • Patent number: 7936832
    Abstract: An ICI cancellation iterative receiver and an ICI cancellation method in the wireless communication system is provided. In order to eliminate the Inter-carrier-interference (ICI) due to phase noise, an adaptive ICI cancellation scheme based on the wireless communication system is presented. In order to correct the contaminated preamble symbols due to phase noise, a first LMS adaptive filter in the receiver cancels the ICI. In the following data symbols of a frame, joint of the turbo decoder and channel estimation is provided. The complexity of the joint algorithm is analyzed and the algorithm can be implemented in the wireless communication system. The simulation results show that the performance can be improved dramatically.
