Abstract: A wireless system broadcasts data in frames, each frame having F slots. Output from a matched filter is used to combine K slots to generate profile data, where K is less than F. N peak values respectively from n peak positions are selected from the profile data, where n is greater than one. A correlator is employed, together with the n peak positions and S slots subsequent the K slots, to generate n×S correlation values. Respective combination values for the n peak positions are generated by coherently combining the correlation values, and combining the coherent combination results with the non-coherent n peak values. The combination values are respectively used to generate SNR values for each of the n peak positions. The peak position having the best respective SNR value is then selected as a slot synchronization position.

Abstract: A source driver and an internal data transmission method are provided. The present invention employs specially designed switch units and creates specially designed data paths in a source driver, which matches with the driving method for dot invesion and the specially designed pixel array. When the dot inversion driving method is used on a pixel array of a specific design, each output buffer and digital-to-analog converter inside the source driver continuously output voltages of positive polarity and voltages of negative polarity, instead of switching between positive and negative polarities. Consequently, the swing voltages that the source driver outputs can be lowered, the power consumption can also be reduced accordingly, a smaller area is occupied, and the costs are reduced.
