COMMUNICATION CHANNEL CALIBRATION USING FEEDBACK
First Claim
1. A method for calibrating in a system including a communication channel coupled to a first component and a second component, the first component having a transmitter with an adjustable parameter, the second component having a receiver, comprising:
- transmitting a data signal from the first component to the second component on the communication channel, the data signal including a sequence of data symbols representing data;
sensing on the second component a characteristic of the data signal and the data represented by the data symbols;
feeding back information about the sensed characteristic from the second component to the first component using a different communication channel; and
adjusting the adjustable parameter for the transmitter on the first component in response to the information about the sensed characteristic.

Abstract
A method for calibrating a communication channel coupling first and second components includes transmitting a data signal from the first component to the second component on the communication channel, and sensing a characteristic, such as phase, of the data signal on the second component. Information about the sensed characteristic is fed back to the first component using an auxiliary channel. An adjustable parameter, such as phase, for the transmitter is adjusted on the first component in response to the information. Also, a characteristic of a data signal received from the transmitter on the second component is sensed and used to adjust an adjustable parameter for the receiver on the first component.
