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.

摘要： An apparatus for providing a multi-mode interface between a baseband receiver and radio frequency (RF) circuitry. According to a preferred embodiment of the invention, the apparatus includes a first differential-to-single-ended converter, a second differential-to-single-ended converter and an analog-to-digital converter. The first differential-to-single-ended converter receives an incoming differential current pair to be converted into a first single-ended voltage signal. The second differential-to-single-ended converter receives an incoming differential voltage pair to be converted into a second single-ended voltage signal. Further, the analog-to-digital converter selectively receives an incoming single-ended voltage signal, the first single-ended voltage signal, or the second single-ended voltage signal to be converted into a digital signal to be further processed by the baseband processor. Note that the incoming single-ended voltage signal, as well as the incoming differential voltage and current signal pairs together form the multi-mode interface to the RF circuitry.

摘要： A method and a device for detecting a preamble type of a wireless data frame are provided. The preamble has a synchronization (SYNC) field and a start frame delimiter (SFD) field, and the method comprises following steps. The wireless data frame is first received, and then determined whether the wireless data frame has a short preamble. When the wireless data frame has the short preamble, the wireless data frame is transmitted to a MAC device. In addition, if the wireless data frame does not have the short preamble, it determines whether the wireless data frame has a long preamble. When the wireless data frame has the long preamble, the wireless data frame is then transmitted to the MAC device.
