Telecommunications > Transmitter > Plural Separate Transmitters Or Channels Plural Separate Transmitters Or ChannelsPlural Separate Transmitters Or Channels 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.11/23/06 - 20060264185 - Communications method, apparatus and signal In a system (e.g. a IR or RF based wireless remote control system) comprising a number (N) of non-synchronized transmitters that transmit respective signals, a method of transmitting data in packets to a receiver, comprising the steps of: transmitting the respective signals, said signals having repeated burst periods that are ... 11/16/06 - 20060258305 - Method and system for transmission of carrier signals between first and second antenna networks Method and system for transmission of carrier signals, each of which occupy a different radio-frequency band, between first and second antenna networks (14, 15), each comprising a plurality of distributed antenna's (6), with the first antenna network (14) being coupled to a main coupling device (3) and to an intermediate ... 10/05/06 - 20060223461 - Digital broadcast methods and apparatus A transmitter apparatus, e.g., at a base station, transmits program information using a plurality of carriers with at least some of the carriers having different transmit power levels. The carrier associated with the highest transmit power level conveys broadcast information carrying basic program information. A carrier associated with a lower ... 08/17/06 - 20060183440 - Digital transmitter and method A transmitter and method is provided for digitally upconverting a baseband digital signal to a modulated intermediate frequency (IF) digital signal and sigma-delta modulating the IF digital signal. The baseband digital signal is split into N phases, as can be accomplished using a polyphase interpolation technique (polyphase filter), and modulated. ... 08/03/06 - 20060172713 - Radio communication system performing multi-carrier transmission, reception device, reception method, transmission device, transmission method, delay time calculation device, and delay time calculation method Multi-carrier transmission is performed without inserting a repetitive signal into guard interval periods. A transmitter provides guard interval periods by using a null signal to save transmission power and prevent the deterioration of the SN ratio. Delayed waves at the head of each received symbol cause high-frequency waves to occur ... 07/20/06 - 20060160498 - Multi-carrier transmitting apparatus and multi-carrier transmitting method A coding section 101 turbo-codes transmit data and outputs parity bit data, and systematic bit data for which good quality is required. A modulation section 102 modulates the parity bit data and systematic bit data. A subcarrier allocation section 103 rearranges the transmit data so that systematic bit data is ... 06/29/06 - 20060141954 - Slice based architecture for a multifunction radio An electronic radio system multifunction slice (100) for a electronic radio system (400). The slice (100) includes an antenna interface (102), several multi-band transceivers. (106-112), a processor (104), and an avionics interface (114). The antenna interface (102) couples to the antenna preconditioners of the aircraft. The processor (104) is coupled ... 06/01/06 - 20060116087 - Control of power amplifiers in devices using transmit beamforming A transmitter comprises a plurality of transmit antennas for simultaneously transmitting weighted signals according to a channel transfer function. Each antenna has a corresponding amplifier that is bias controlled according to the transmit weights derived for the antenna transmission. A baseband processor produces digital weighted signals for upconversion and amplification ... 06/01/06 - 20060116086 - Circuit and method for transmitting a signal A circuit for transmitting a signal has a first signal line and a second signal line, wherein the second signal line is arranged adjacent to the first signal line, such that an interaction between signals being transmitted on the signal lines takes place. The circuit further comprises a first driver ... 05/25/06 - 20060111056 - Electronic antenna beam steering using ancillary receivers and related methods Communications device may include a plurality of antenna elements, an ancillary control receiver, and a primary receiver. The plurality of antenna elements may provide respective fixed beams. The ancillary control receiver may be coupled to each of the antenna elements, and the ancillary control receiver may be configured to measure ... 04/27/06 - 20060089109 - Transmitting apparatus of communication system A transmitting apparatus according to the present invention includes a prefilter for compensating a previously measured estimated impulse response of a communication system by assuming a communication system in which the transmitting apparatus and the receiving apparatus are directly connected. The prefilter included in the transmitting apparatus compensates an original ... 10/20/05 - 20050233711 - Multi-carrier transmission device and multi-carrier transmission method During the time when a mobile station of a communicating party receives a signal from another base, a synchronization control section 101 instructs stop of signal transmission to a control section 102-1, which corresponds to a system that transmits a signal with carrier frequency f1 at which a signal is ... 07/14/05 - 20050153669 - Timing adjustment method for wireless communication apparatus The linearity of a transmission signal is improved in a wireless communication device by adjusting a delay difference between paths of two signals that are combined into one after modulation through the paths of different delay amounts, such as an r signal and a θ signal in EER. A transmitter ... ### FreshPatents.com Support |
