20080280449	SELF-ALIGNED DIELECTRIC CAP - A method of forming a dielectric layer includes providing a substrate that has a copper region and a non-copper region. The substrate is etched to remove any copper oxides from the copper region. A dielectric cap is then selectively formed over the copper region of the substrate so that little or no dielectric cap is formed over the non-copper region of the substrate.	11-13-2008

20100183098	METHOD AND SYSTEM OF DIFFERENTIAL COMPLEX AND REAL MULTI-CARRIER DEMODULATION - A method and a receiver are provided for demodulating a received multi-carrier modulated signal. The demodulation procedure includes (a) multiplying the received multi-carrier modulated signal with its complex conjugate to obtain a squared signal; (b) multiplying the squared signal with a signal having a frequency	07-22-2010

20090046792	METHOD AND SYSTEM OF TIME-OF-ARRIVAL ESTIMATION FOR ULTRA WIDEBAND MULTI-BAND ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING SIGNALS - A time-of-arrival (TOA) estimation method for multi-band orthogonal frequency division multiplexing (MB-OFDM) signals uses a simple equally-spaced channel model to recover the impulse response of the wireless channel, and locates the delay of the first channel path by minimizing the energy leakage from the first channel path. The TOA is estimated based on the delay. Such a method does not require channel information for TOA estimation at the receiver and does not require modification of the receiver structure. The method also avoids a sub-optimal solution known to occur in maximum likelihood (ML) estimation.	02-19-2009
