    Abstract: The present invention discloses a method and apparatus of IQ imbalance compensation for a receiver. The repetitive attribute of the preamble in a signal received by the receiver is used to estimate the IQ imbalance parameters. The data carried by the preamble repeats itself every N sampling intervals. A MSE equation is derived based on assuming the ratios between any two sampling points separated by N samples are identical, and the IQ imbalance parameters can be estimated by solving the MSE equation using the LS algorithm. Consequently, the IQ mismatch offset of the signal is compensated according to the estimated parameters.

    Abstract: A novel apparatus for compressing viscous material through openings in a stencil is disclosed. The novel apparatus has a compression headcap which provides a contained environment to direct and to aid the flow of pressurized viscous material through the openings in the stencil. The compression headcap includes two generally parallel wiper blades that are biased into sliding communication with the stencil. Longitudinal diffuser plates guide and equalize the flow of the viscous material into the volume between two generally parallel wiper blades.

    Abstract: A method for implementing an equalizer of an orthogonal frequency division multiplexing (OFDM) baseband receiver is provided. The OFDM baseband receiver includes a channel estimation and tracking module for estimating a channel impulse response of an input signal of the equalizer. A conjugate of the channel impulse response is first calculated. The input signal and the conjugate of the channel impulse response are then multiplied to generate a product signal. The product signal is then taken as the output signal of the equalizer without dividing the product signal by a channel state information, wherein the channel state information represents a square of an absolute value of the channel impulse response.

    Abstract: The invention provides a method for controlling the signal gain of a MultiBand Orthogonal Frequency Division Multiplexing (MB-OFDM) baseband receiver. The symbol boundary of a signal is first detected. Power of the signal is then measured according to the symbol boundary, so that a zero-padding section of the signal is not measured. A gain magnitude for amplifying the signal is then determined according to the power of the signal. The signal is then amplified according to the gain magnitude.

    Abstract: A method and an apparatus of compensating for a signal receiving error at a receiver in a packet-based communication system. In the invention, frequency offset estimation and DC offset estimation obtained in a current packet are re-used in a next packet if the receiver is an intended recipient of the current packet and the current packet is received correctly, verified by CRC-32 checking in the PHY layer and the DA checking in the MAC layer, respectively. Thereby, the overall receiver performance and stability can be improved from packet to packet and the estimation algorithm is simplified.
