Abstract: In encoding systems and methods, data or information is encoded using one or more encoding methodologies to generate encoded data or information corresponding to the data or information. Similarly, in decoding systems and methods, encoded data or information is decoded using one or more decoding methodologies to generate the data or information corresponding to the encoded data or information. The encoding/decoding systems and methods can include polar encoding/decoding systems and methods operable for encoding data or information to generate polar codes and for decoding polar codes to generate the corresponding data or information. The information or data can be control information and application data for communication over networks. The networks can include wireless and wireline networks, and network segments, links or channels, including mixed wireline and wireless networks.

Abstract: Various embodiments of the invention may use the state of the output of a light sensor to permit transmission of an identification code from an activated radio frequency identification (RFID) tag. Alternately, the state of the output of the light sensor may be used to select one of multiple identification codes for transmission from the activated RFID tag.

Abstract: Described are a system and method for processing data received at or to be transmitted through a constituent base station. In one example, a digital signal may be generated based upon an RF signal received at the constituent base station. The digital signal may be encapsulated in data frames for transmission in a SONET circuit to a processing station. The processing station may recover the digital signal from received data frames and perform base-band processing on the recovered digital signal.

Abstract: A leaky transmit/receive switch may be used in a transceiver to permit the receiver to receive a portion of transmitted signal energy.

Abstract: A method and apparatus for time varying filtering of an audio signal without introducing audible artifacts is presented. The method comprises filtering a segment of the signal using a given filter, and then disengaging the filter in a sequence of graduated steps at the end of the segment. To then filter the next segment of the input signal with a different filter, the new filter is gradually engaged in a sequence of steps at the beginning of such next segment of the input signal. The remainder of the signal in the segment is filtered with the fully engaged filter, until the end of the segment, where it is gradually disengaged, as was the prior filter. The method of switching filters by gradually disengaging a given filter at the end of signal segments and gradually engaging the next filter at the beginning of the next segment is repeated until the entire input signal has been processed. Such method obviates audible artifacts in the filtered signal, while enabling the time varying filtering of an input signal.
