摘要： Vehicle segmentation and counting method based on the property of color variation and headlight information combining change detection in nighttime traffic environment (one-way road with coming direction) is provided. The goal is to reduce the effect of ground-illumination that decreases the accuracy of vehicle segmentation. Besides, the amount of traffic flow is calculated and it can be used in other post-applications, such as traffic-flow reporting or controlling.

摘要： A system and method for transmitting data in multiple-branch transmitter-diversity OFDM systems is presented. In one embodiment, an approach is taken where an inverse Fourier transform (IFT) is performed on data prior to encoding the data for transmission in the multiple-branch transmitter-diversity system. In another embodiment an IFT is performed on data prior to encoding the data using a space-time block code (STBC) algorithm.

摘要： A method is directed to recovering a digital data content in a communication system, wherein the digital data content has been converted into an analog signal based on a primary clock, at a transmitter for transmitting to a receiver. The method comprises receiving the analog signal by the receiver. The analog signal is converted into a digital signal, based on a clock of the receiver. The digital signal is interpolated at the desired interpolation point, if digital signal in time has been shifted by an amount equal to or larger than a predetermined time length. The interpolated digital signal is recovered back to the digital data content, with the assist of an estimated channel impulse response. The channel impulse response is retrained every time when the interpolation point is significantly changed.
