Telecommunications > Transmitter And Receiver At Separate Stations > Frequency Or Phase Modulation Frequency Or Phase ModulationFrequency Or Phase Modulation patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.01/25/07 - 20070021068 - User applied template cover for hand-held music player An adhesive plastic cover for, and in combination with, a hand held portable audio music playback electronic device is preshaped to cover at minimum the front, rear, top and bottom surfaces of the music playback device. A strip in a midsection of the cover corresponds to the top surface of ... 12/14/06 - 20060281410 - Methods and apparatus to integrate image rejection into quadrature mixers Methods and apparatus to integrate image rejection into quadrature mixers are disclosed. A disclosed image-rejection quadrature mixer comprises a quadrature mixer, and a cross-coupled differential pair of transistors to provide a complex filter response, wherein the mixer and the transistors are integrated on a common silicon substrate. ... 11/16/06 - 20060258290 - System and method for detecting a device requiring power A system and technique for detecting a device that requires power is implemented with a power detection station. The power detection system includes a detector having an output and a return which are coupled together by the device when the device requires power. The detector includes a word generator for ... 06/01/06 - 20060116077 - Exploiting multiuser diversity through phase modulation multiplexing A method and apparatus for combining signals of multiple users onto a common channel is disclosed. In one embodiment, the method comprises identifying one or more traffic channels that are of one or more predetermined quality levels to a plurality of subscriber units based on channel profiles of the plurality ... 03/30/06 - 20060068707 - Frequency selective leveling loop for multi-signal phased array transmitters A frequency selective leveling loop that performs phase and amplitude control of multiple signals within a phased array structure is disclosed. The leveling loop sensor componants are embedded into the array structure. The frequency selective leveling loop can be used with multiple signal amplifiers, and a conventional phase array jamming ... 11/10/05 - 20050250450 - Cellular communications system using baseband carrier injection and related methods A cellular communications system may include one or more cellular base stations and a plurality of mobile cellular communications devices for communicating therewith. More particularly, the cellular base station and the mobile cellular communications devices may each include an encoder for generating an information signal. Furthermore, a modulator may generate ... 09/08/05 - 20050197065 - Adaptive modulation scheme and data rate control method A transmitter station and receiver station have common maximum number of transmission bits per symbol of each subcarrier and information of encoding types to be selected. The transmitter station selects the modulation type from the propagation path quality of each subcarrier, executes the encoding with the encoding type corresponding to ... ### FreshPatents.com Support |
