Abstract: A WLAN communication system (10) and method employs mobile WLAN base stations (16) that include WLAN transceivers (26) and memory (30) for storing received messages from one or more mobile WLAN devices (12a-12n). The mobile WLAN base stations (16) serve as moving message carriers or message repeaters of messages for the mobile WLAN devices. In one embodiment, a mobile WLAN base station (16) receives messages transmitted by several mobile WLAN devices (12a-12n), temporarily stores the received messages, and delivers the stored messages to a fixed WLAN base station or another mobile WLAN base station when the mobile WLAN base station (16) moves to within communication range of the applicable fixed or other mobile WLAN base station.

Abstract: A method and system is provided for determining a location for each of a plurality of units, which is selected from one of multiple sets of locations, which are each estimated based upon different initial location estimates. The selected set of locations includes the set which has the minimum error value, where the error value is based on the aggregate of the differences between the range determined from the estimated locations and the measured range. By using different sets of initial location estimates, there is a greater chance that at least one of the sets of initial location estimates will avoid any local minimums and produce a more accurate estimate of unit locations.

Abstract: A method (500) and system for compensation of frequency offset between a first transceiver (102) and a second transceiver (104) in wireless communication are disclosed. The compensation of the frequency offset between two or more transceivers (102, 104) is achieved by transmitting a set of frequency synchronization bursts. These bursts contain information about the frequency offset. The frequency synchronization bursts are transmitted by the first transceiver at a range of frequencies above and below its carrier frequency (502). When system conditions permit, a subset of the set of frequency synchronization bursts may be transmitted instead of transmitting the full set of frequency synchronization bursts.

Abstract: A method is provided for acquiring channel viewership information in a content delivery system. The method begins by receiving a plurality of messages over an access network each indicating that a subscriber is switching to a specified broadcast channel. The information obtained from the messages is aggregated to generate channel viewership information identifying a number of subscribers tuned to each broadcast channel over a period of time. The channel viewership information is presented in a selected format.

Abstract: During operation of a node in a secondary communication system (100) data enters a spreader (301) and is appropriately spread. The spread data is then modulated onto all available channels using a multi-carrier OFDM modulation technique. This entails the spread data being modulated onto those channels that are currently being used by the primary communication system (120). Finally, a transmitter (303) transmits the spread data only over carriers that will not interfere with the primary communication system.

Abstract: A direct sequence spread spectrum (DSSS) receiver (100) consistent with certain embodiments has a frequency generator (112) that generates a local oscillator signal without use of a piezoelectric crystal. A frequency converter (108) receives the local oscillator signal and mixes the local oscillator signal with a received DSSS signal to produce a down-converted signal. The received DSSS signal is encoded using a first set of DSSS code. A differential chip detector (116) receives the down-converted signal and converts the down-converted signal to a differentially detected signal. A correlator (120) receives the differentially detected signal and correlates the detected signal with a set of DSSS codes that are time-shifted from the first set of DSSS codes. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

Abstract: During operation of a secondary communication system (100), a random exponential back off for future sync bursts will be executed following the detection of an unauthenticated beacon. More particularly, a cognitive radio (104) acts on every sync burst received, until acting on one results in the reception of no beacon or an unauthenticated beacon. The cognitive radio then begins a random exponential back off procedure, in which it must receive a random number of sync bursts before it will schedule time to receive a beacon. For each unauthenticated beacon received, the back off exponent is incremented, thereby increasing the number of sync bursts that must be received before it will schedule time to receive a beacon again.

Abstract: A wireless communication network (100) employs a method and apparatus for reliably communicating information packets in the network. A first wireless device (101) in the network transmits an information packet to a second wireless device (e.g., 102) in the network over a first wireless communication channel (403, 404). The first device then determines whether the information packet was successfully received (e.g., received without errors) by the second device. If the information packet was not successfully received, the first device retransmits the information packet to the second device over a second wireless communication channel (405, 406). In addition, and preferably substantially contemporaneous with retransmission of the first information packet, the first device transmits a second information packet to the second device over the first channel in an effort to communicate an information sequence to the second device without delays typically associated with use of a reliable protocol.

Abstract: The present invention provides a multimode receiver design for mitigation of frequency offset by selective demodulation of an input modulated signal. The receiver (103) comprises a plurality of demodulators (207). Each of the plurality of demodulators (207) has the same functionality but different receiver sensitivity versus frequency-offset mitigation characteristics. Each of these demodulators incorporates a different demodulation technique. A suitable demodulator is selected to demodulate the received signal. The choice of a suitable demodulator is based on the value of the frequency offset (305, 307).
