Title:
CLOCK TONE POWER BOOSTING
Document Type and Number:
WIPO Patent Application WO/2017/071452
Kind Code:
A1
Abstract:
A digital signal processing apparatus and method is described for a transmitter of a communication link. The digital signal processing apparatus comprises a pre-compensation filter for boosting power of a signal to be transmitted within two predetermined frequency bands. One of the predetermined frequency bands is centered around a clock tone frequency of fbaud/2, and the other one of the predetermined frequency bands is centered around a clock tone frequency of -fbaud/2, fbaud being a baud rate of the transmitted signal.
