PULSE SHAPING FOR RADIO FREQUENCY TRANSMITTERS

摘要

Transients caused by load modulation can fee compensated far by adjusting pulse shapes. A radio frequency (RP) carrier signal can be modulated using load modulation. For the modulated RF carrier signal a particular pattern can be detected for a symbol period that precedes a second symbol that does not use load modulation. In response to the detecting, a pulse shape of the first symbol can be adjusted to mitigate the transients.

1. A method for compensating for transients caused by load modulation by adjusting pulse shapes, the method comprising:
modulating a radio frequency (RF) carrier signal using load modulation; detecting, for the modulated RF carrier signal, a particular symbol pattern for a first symbol that includes a plurality of pulses and that precedes a second symbol that does not use load modulation; and adjusting, in response to the detecting, a pulse shape of the first symbol to mitigate the transients.
