Abstract: Method and system to utilize the set of navigation paths of web pages as the contextual information for subject relevant web page filtering with high accuracy are provided. The method comprises the steps of: obtaining all web pages in one or more web pages collections; collecting information of the links among the obtained web pages; extracting, based on the collected links, a set of navigation paths of each of the obtained web pages; and filtering the obtained web pages based on the extracted set of navigation paths to obtain desired web pages. In some embodiments, the extraction of the navigation paths is preferably performed on the navigation links of the web pages. Therefore, the method also comprises the process for deleting non-navigation links from all the links of the web pages. Compared with the prior art, the present invention can utilize the contextual information of the web pages for web page filtering in a more sufficient way, thereby improving the accuracy and objectivity of the web page filtering.

Abstract: A method of decoding a plurality of diverse signals for low-density parity-check (LDPC) decoders that takes advantage of signal diversity. The method allows for the combining of soft-decision LDPC encoded non-coherently modulated signals, which is in contrast to existing approaches where hard decision combining is used for non-coherently modulated signals. The method includes the steps of inputting each diversity signal into a unique demodulator, and calculating the LLR of each demodulated signal. When the diverse demodulated signals are combined into a single combined signal, each bit of the combined signal is selected according to the value of either the highest LLR value of each bit across the demodulated signals or according to the sum of the LLR of each bit across the demodulated signals.

Abstract: A wireless device with power amplifiers having different characteristics to support transmission on multiple antennas is disclosed. These power amplifiers may have different gain, different maximum output power levels, etc. in order to meet requirements of different wireless systems. In an exemplary design, an apparatus includes first and second power amplifiers having different characteristics. The first power amplifier amplifies a first input signal and provides a first output signal for a first antenna. The second power amplifier amplifies the first input signal or a second input signal and provides a second output signal for a second antenna, e.g., in a MIMO mode or a transmit diversity mode. Only the first or second power amplifier amplifies another input signal and provides another output signal to the first antenna, e.g., in a CDMA mode or a GSM mode.
