摘要： A spread spectrum system may include a transmitter and a receiver. The transmitter is configured to transmit a signal having at least one channel, where the signal may include a reference signal, an information signal and a frequency offset between the reference signal and the information signal. The receiver may receive the transmitted signal from the transmitter and mix the received signal in order to retrieve the information signal from the received signal. This allows the receiver to operate at low power (e.g., 10 uW-100 uW).

摘要： Methods, apparatus, and systems are described, in which mobile stations in gaps between conventional cells obtain access to high speed data services by initiating an ad hoc, peer-to-peer connection with an intermediary mobile station and transmitting an access request message to the intermediary mobile station for relaying to a nearby base station. Upon receiving such an access request, a base station determines the approximate location of the mobile station, estimates an angular direction from the base station to the mobile station, and forms a directed antenna beam aimed towards the mobile station for transmission of high speed data to the mobile station. Corresponding techniques in which a base station initiates the establishment of a high speed data link are also disclosed.

摘要： Two or more video streams including a high quality video stream and a low quality video stream are simultaneously transmitted to the mobile communication device over the wireless network. All of the video streams carry the same video content but with different video quality. The high quality video stream is transmitted with a relatively low margin and the low quality video stream is transmitted with a relatively high margin. The mobile communication device can select the high quality video stream when channel conditions are favorable, and may select the low quality video stream when the channel conditions are not good enough to support the high quality video stream.

摘要： A mobile terminal reduces power consumption when operating at a high transmit power by altering a modulation scheme used for transmitting signals over an uplink to a base station. The mobile terminal receives uplink load indications from the base station and determines it current transmit power level. Based on this information, the mobile terminal selects an appropriate modulation scheme.

摘要： The wireless communication device and corresponding method described herein selectively switches between a single-frequency mode, such as appropriate for an EDGE network, and a multiple-frequency mode, such as appropriate for a multi-carrier EDGE network. Accordingly, a transmitting wireless communication device selectively switches between a single-channel mapping unit, used during the single-frequency mode, and a multi-channel mapping unit, used during the multiple-frequency mode. The multi-channel mapping unit modulates input data to output a modulated data stream for each of multiple adjacent frequency channels that, when combined, produce a multiple-frequency signal with reduced peak-to-average ratio. A receiving wireless communication device selectively switches between a single-channel demodulator, used during the single-frequency mode, and a multi-channel demodulator, used during the multiple-frequency mode.

摘要： A method and a system are provided for controlling a controller without physically touching the controller. A hand or other object interacts with a field surrounding the controller, altering the field. A change in characteristic of the altered field causes a corresponding movement of the controller that, in turn, corresponds to an amount of change in a parameter of a target device being controlled by the controller. The parameter of the target device is controlled by the controller while a user has no physical contact with the controller.
