Abstract
Various embodiments are described that relate to radio beamforming waveform transmission. Transmission can occur, for example, in three manners. The first manner is time-based where waveform transmission is staggered at the same frequency. The second manner is frequency-based where different frequencies are used at one time. This third manner is a combination of time and frequency such that simultaneous transmission occurs, but at different times different frequencies are used.
Claims20
A system, comprising:
- a signal analysis component configured to analyze a first signal for transmission by a first antenna and a second signal for transmission by a second antenna, different from the first antenna, to produce a signal analysis result;
- a selection component configured to select a pulse compression technique from among a time-shifted only duplex pulse compression technique, a frequency-shifted only duplex pulse compression technique, or a time-shifted and frequency shifted duplex compression technique;
- and
- a non-transitory computer-readable medium configured to store a command set executable by a processor to facilitate operation of the analysis component, the selection component, or a combination thereof,
- where the selection is based, at least in part, on the signal analysis result,
- where the first antenna is configured to transmit the first signal subjected to the selected pulse compression technique,
- where a second antenna is configured to transmit the second signal subjected to the selected pulse compression technique,
- where the first antenna is configured to transmit the first signal and the second antenna is configured to transmit the second signal, at least in part, simultaneously,
- where the first antenna is configured to transmit the first signal in a frequency band, and
- where the second antenna is configured to transmit the second signal in the frequency band.
