Abstract

Data communication for wired and or for wireless communication and broadcasting systems for broadband, ultra wideband and ultra Narrowband (UWN) reconfigurable, interoperable communication and broadcasting system architectures. Combinations and hybrids of ultra wideband (UWB), ultra narrowband (UNB) and efficient broadband wireless, baseband, intermediate frequency (IF) and radio frequency (RF) implementations for Bit Rate Agile (BRA) reconfigurable and interoperable systems. Processing the data signals, of clock signals, and/or carrier cycles waveforms leads to shaped radio-frequency (RF) cycles, waveforms and wavelets.

Claims

a frequency generator for generating a carrier frequency signal;

means for reversing the phase of said carrier frequency signal;

selection means for selecting and providing the generated carrier frequency signal or the reversed phase carrier frequency signal for subsequent filtering and transmission;

processing means of the data signals to generate control signals;

control means to provide selection of said carrier frequency signal or of said reversed phase carrier frequency signal;

said control means to select the reversed phase carrier frequency signal only for one of the binary data states and to select the carrier frequency signal for the other binary data state; and

control signal logic means to select majority fraction of a bit period duration of the phase carrier frequency signal and minority fraction of a bit period of the reversed phase carrier frequency signal or to select minority fraction of a bit period duration of the phase carrier frequency signal and majority fraction of a bit period of the reversed phase carrier frequency signal.

2. A method of transmitting digital data in a wireless communications system, the method comprising:

phase shift keying a carrier frequency of a signal used for transmitting and/or receiving digital data, and

processing the said modulated information in a spread spectrum structure to spread the said modulated information

3. An apparatus for transmitting data comprising:

carrier waveform generating means for generating a carrier waveform having a specified amplitude shape and specified time;

code generating means, coupled to said carrier waveform generating means, for generating groups of carrier waveforms in accordance with a predefined code; and

data encoding means for modifying the phase of said carrier waveform as a function of said data to be transmitted.
