  • Method and device for mitigating interference in collocated transceivers
    Patent number: 10425950
    Abstract: The disclosure relates to a method for mitigating interference of a first radio signal received by a first transceiver of a first radio access technology (RAT) due to transmission of a second radio signal by a second transceiver of a second RAT, wherein the first transceiver and the second transceiver are physically collocated on a same device. The method includes: pre-setting a power of the second radio signal based on a throughput performance requirement for the first radio signal before transmission of the second radio signal, and tuning the power of the second radio signal during transmission of the second radio signal based on estimating the interference of the first radio signal.

  • Channel estimation for ofdm systems
    Publication number: 20070110172
    Abstract: A method for performing channel estimation in an orthogonal frequency-division multiplexing system, the method including the steps of: receiving (80) transmitting pilot symbols from a plurality of transmit antennas; forming (82) a least-squares estimation matrix from the transmitted pilot symbols; forming (8488) a sparse smoothing matrix approximating a fixed weighting matrix, wherein each row vector in the sparse smoothing matrix contains one or more of the strongest weights in each row of the fixed weighting matrix; and (90) deriving a channel estimation matrix from the sparse smoothing matrix and the least-squares estimation matrix.
