Abstract
A receiver includes first and second equalization modules adapted to provide first and second compensations to a data signal, and a control module including a list that identifies the first equalization module as being less efficient than the second. The control module provides first and second compensation levels of the first and second compensations, such that the first and second compensations operate on the data signal to meet a bit error rate (BER) target, lowers the first compensation to reduce the power consumption of the receiver based on the list, and determines whether, in response to an increase in the level of the second compensation the BER target is met.
Claims20
A receiver, comprising:
- a first equalization module adapted to provide a first compensation to a data signal received by the receiver;
- a second equalization module adapted to provide a second compensation to the data signal;
- and
- a control module including a first list that identifies the first equalization module as being less efficient than the second equalization module, the control module adapted to:
- provide a first compensation level of the first compensation and a second compensation level of the second compensation, such that the first compensation level and the second compensation level combine to operate on the data signal to meet a bit error rate (BER) target;
- set the level of the first compensation from the first compensation level to a third compensation level to reduce a power consumption of the receiver based on the first list identifying the first equalization module as being less efficient than the second equalization module;
- and
- determine whether, in response to an increase in the level of the second compensation from the second compensation level to a fourth compensation level, a combination of the third compensation level and the fourth compensation level operate on the data signal to meet the BER target.
A method, comprising:
- providing, by a control module of a receiver, a first compensation level of a first compensation to a data signal received by the receiver, the first compensation being provided by a first equalization module of the receiver, and a second compensation level of a second compensation to the data signal, the second compensation being provided by a second equalization module of the receiver, such that the first compensation level and the second compensation level combine to operate on the data signal to meet a bit error rate (BER) target;
- setting, by the control module, the level of the first compensation from the first compensation level to a third compensation level to reduce a power consumption of the receiver based on a first list identifying the first equalization module as being less efficient than the second equalization module;
- and
- determining, by the control module, whether, in response to an increase in the level of the second compensation from the second compensation level to a fourth compensation level, a combination of the third compensation level and the fourth compensation level operate on the data signal to meet the BER target.
A non-transitory computer-readable medium including code for performing a method, the method comprising:
- providing, by a control module of a receiver, a first compensation level of a first compensation to a data signal received by the receiver, the first compensation being provided by a first equalization module of the receiver, and a second compensation level of a second compensation to the data signal, the second compensation being provided by a second equalization module of the receiver, such that the first compensation level and the second compensation level combine to operate on the data signal to meet a bit error rate (BER) target;
- setting, by the control module, the level of the first compensation from the first compensation level to a third compensation level to reduce a power consumption of the receiver based on a first list identifying the first equalization module as being less efficient than the second equalization module;
- and
- determining, by the control module, whether, in response to an increase in the level of the second compensation from the second compensation level to a fourth compensation level, a combination of the third compensation level and the fourth compensation level operate on the data signal to meet the BER target.
