Abstract
Technologies are generally described for a bandwidth control scheme. In some examples, a transmitter device configured to transmit information via a wireless connection may include a baseband signal processor configured to process the information to generate a baseband signal with a baseband bandwidth; a modulator configured to modulate a radio frequency (RF) signal with an RF bandwidth based on the baseband signal; and a controller configured to adjust at least one of the baseband bandwidth and the RF bandwidth based on a movement of the transmitter device relative to a position of a receiver device configured to receive the RF signal.
Claims20
A portable transmitter device configured to transmit information via a wireless connection, the portable transmitter device comprising:
- a baseband signal processor configured to process the information to generate a baseband signal with a baseband bandwidth;
- a modulator configured to modulate a radio frequency (RF) signal with an RF bandwidth, wherein the modulation is based on the baseband signal;
- and
- a controller configured to correct respective Doppler effect-induced bandwidth shifts by reduction in the baseband bandwidth and the RF bandwidth based on a moving speed of the portable transmitter device relative to a position of a receiver device that is configured to receive the RF signal.
A method to transmit information via a wireless connection in a portable transmitter device, the method comprising:
- processing, by a baseband signal processor, the information to generate a baseband signal with a baseband bandwidth;
- modulating, by a modulator and based on the baseband signal, a radio frequency (RF) signal with an RF bandwidth;
- and
- correcting, by a controller, respective Doppler effect-induced bandwidth shifts by reducing the baseband bandwidth and the RF bandwidth based on a moving speed of the portable transmitter device relative to a position of a receiver device configured to receive the RF signal.
A non-transitory computer-readable storage medium which stores a program to cause a processor to transmit information via a wireless connection in a portable transmitter device, the program comprising one or more instructions to:
- process, by a baseband signal processor, the information to generate a baseband signal with a baseband bandwidth;
- modulate, by a modulator and based on the baseband signal, a radio frequency (RF) signal with an RF bandwidth;
- and
- correct, by a controller, respective Doppler effect-induced bandwidth shifts by reduction in the baseband bandwidth and the RF bandwidth based on a moving speed of the portable transmitter device relative to a position of a receiver device configured to receive the RF signal.
