  • Publication number: 20060017626
    Abstract: An antenna module for use with a mobile telecommunication device such as a mobile phone. The antenna module includes an antenna element and, preferably, an RF (radio frequency) chain having receive circuitry and perhaps an analog-to-digital converter or other electrical components. Transmit circuitry may be present as well. The antenna module has a housing, in one or more parts, for supporting these components, and a jack through which power and data links can be formed. The jack may provide a means for adjusting the antenna so that its orientation relative to the mobile phone antenna may be altered.

  • Publication number: 20050117532
    Abstract: In the reception of a CDMA signal, the receiving unit performs a simplified process of linear equalization that eliminates the need for inverting the correlation matrix. For the single antenna reception case, the correlation matrix is approximated to a good degree by a circulation matrix that is diagonalized by FFT operations, thus substituting two FFTs and one IFFT having a complexity of O(3/2 LF log LF) for the direct matrix inversion having a complexity of O(LF3). The extension of this method uses a multiple antenna reception system with oversampling.

  • Patent number: 6873596

For the single antenna reception case, the correlation matrix is approximated to a good degree by a circulation matrix that is diagonalized by FFT operations, thus substituting two FFTs and one IFFT having a complexity of O({fraction (3/2)}LFlog LF) for the direct matrix inversion having a complexity of O(LF3). The extension of this method uses a multiple antenna reception system with oversampling.
