Abstract:
1. A method of receiving data from a data-carrying signal transmitted by a transmitter, comprising: using an automatic gain controlled amplifier at the receiver to amplify the data-carrying signal to a predetermined level, the automatic gain controlled amplifier including a variable gain amplifier and a peaking amplifier, such that in a first mode, the variable gain amplifier amplifies the data-carrying signal to a predetermined level and the peaking amplifier amplifies substantially without peaking, and in a second mode, the variable gain amplifier amplifies with fixed gain and the peaking amplifier amplifies with peaking; receiving values of data bits from the data-carrying signal with equalization at the receiver; generating first information for adjusting an amount of the equalization performed at the receiver; generating second information for adjusting an amount of pre-distortion applied to the data-carrying signal by the transmitter; and transmitting the second information to the transmitter.
