Telecommunications > Transmitter > Carrier Amplitude Control (e.g., Voice Operated On/off) Carrier Amplitude Control (e.g., Voice Operated On/off)Carrier Amplitude Control (e.g., Voice Operated On/off) 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.10/12/06 - 20060229037 - Piecewise linearizer circuit for radio frequency amplification An apparatus and method for amplifying a radio frequency signal including, generating a plurality of shaped pulses utilizing a piecewise linearizer circuit, applying the plurality of shaped pulses to a first input of a radio frequency amplifier circuit, and injecting a radio frequency carrier into a second input of the ... 07/20/06 - 20060160499 - Polar modulator and method for modulation of a signal A modulated carrier signal is produced from a phase modulation signal in a phase locked loop in a polar modulator. This carrier signal is converted via a limiting amplifier to a square-wave signal, which is supplied to an amplifier. At the same time, an amplitude modulation signal at one input ... 07/13/06 - 20060154623 - Wireless telephone with multiple microphones and multiple description transmission The present invention is directed to a multiple description transmission system that provides redundancy to combat transmission channel impairments. The multiple description transmission system includes a first and second wireless telephone. The first wireless telephone includes the following: an array of microphones, wherein each microphone in the array of microphones ... 04/06/06 - 20060073796 - Apparatus for receiving and issuing data through a display on an interior of a passenger compartment of a motor vehicle This invention has as an object a complex multifunctional apparatus for receiving and issuing data through of the visualization of the latter by means of a display or a monitor on the interior of the passenger compartment of a motor vehicle, with a control device and mobile telephone remote control ... 02/16/06 - 20060035606 - Method and apparatus for transmitting and outputting data in voice communication Disclosed is a method and apparatus for transmitting and outputting data in voice communication over a traffic channel. The apparatus includes: a signal generator for generating a low frequency signal corresponding to a key signal inputted during voice communication; a signal synthesizer for synthesizing the low frequency signal and a ... 08/18/05 - 20050181747 - Transmitter of mobile communication terminal A transmitter of a mobile communication terminal including a transmission signal processor for receiving a data signal to be transmitted, modulating the data signal into a radio signal, and outputting the radio signal. A local oscillator device provides the transmission signal processor with a local oscillator signal and a modem ... 08/04/05 - 20050170793 - Wireless communication device A reader/writer of a wireless communication device transmits a carrier signal from an antenna, and if there is not response from an IC card within a preset time after transmitting the polling command, the carrier signal is temporarily controlled to an OFF state. ... ### FreshPatents.com Support |
