    Abstract: A circuit structure has a channel estimator adapted to receive an input, an equalizer adapted to receive the input and generate an equalized output, and an equalizer training block adapted to receive estimated channel condition information, and provide a set of trained coefficients to the equalizer. The equalized output is used by the channel estimator for at least one subsequent channel estimation. The channel estimator, the equalizer, and the equalizer training block are looped together.

    Abstract: An LDPC based TDS-OFDM receiver for demodulating an LDPC encoded TDS-OFDM modulated RF signal downconverted to an IF signal includes a synchronization block, an equalization block, an OFDM demodulation block and a FEC decoder block. The synchronization block generates a baseband signal from a digitized IF signal and performs correlation of a PN sequence in a signal frame of the received RF signal with a corresponding locally generated PN sequence to provide signals for performing carrier recovery, timing recovery and parameters for channel estimation. The equalization block performs channel estimation and channel equalization. The OFDM demodulation block performs demodulation on the baseband signal to recover OFDM symbols and converts the OFDM symbols to frequency domain. The FEC decoder block includes an LDPC decoder for decoding the OFDM symbols based on the LDPC code to generate a digital output signal indicative of the data content of the RF signal.

    Abstract: An LED lamp (100) includes a lamp enclosure (10) and two LED modules (30). The lamp enclosure has a concave housing (11). The housing includes an elongated bottom plate (111) and two lateral plates (115) extending upwardly from two opposite lengthwise sides of the bottom plate respectively. An opening (156) is defined at a top side of the lamp enclosure. The LED modules each are mounted at a joint between the bottom plate and a corresponding of the lateral plates in such a manner that at least a portion of lights emitted by the LED modules is firstly directed to and reflected by an internal surface of the bottom plate, and then directed to an outside through the opening.

    Abstract: Following CMP, a magnetic tunnel junction stack may protrude through the oxide that surrounds it, making it susceptible to possible shorting to its sidewalls. The present invention overcomes this problem by depositing silicon nitride spacers on these sidewalls prior to oxide deposition and CMP. So, even though the stack may protrude through the top surface of the oxide after CMP, the spacers serve to prevent possible later shorting to the stack.
