Abstract
A transmitter comprising a noise signal generator, and a transmit driver coupled to an output of the noise signal generator.
Claims20
A transmitter comprising:
- a noise signal generator;
- and
- a transmit driver coupled to an output of the noise signal generator.
A method of transmitting a signal from a transmit driver, the method comprising:
- receiving a signal comprising a noise signal at the transmit driver;
- and
- generating an output from the transmit driver based on the signal.
A method of calibrating signal-to-noise ratio (SNR) for a transmitter comprising:
- transmitting a first signal comprising a data signal with no noise signal;
- capturing the first signal;
- transmitting a second signal comprising a noise signal;
- capturing the second signal;
- and
- determining the SNR corresponding to the first signal and the second signal, wherein the transmitter transmits the second signal using a transmit driver.
