用于传输电路的可配置预加重组件

Configurable pre-emphasis component for transmission circuitry
Abstract:
A configurable pre-emphasis filter component may be configured based upon measured frequency response (e.g., filter effect) associated with at least one analog filter positioned between a digital predistortion component and a power amplification component of a transmission circuitry. The frequency response may be measured using a calibration signal sent via the transmission circuitry, a loopback circuit, and a reception circuitry. Calibration circuitry may be used with one or more loopback circuits to measure the frequency response of various analog components of the transmission circuitry. The calibration circuitry may also include logic to determine a configuration for the PEF component based upon the measured frequency response.
