Abstract:
A receiver is optimized by adapting parameters of components within the receiver. Various component parameters are adapted by using either a least means squared algorithm or a steepest descent algorithm. The taps of a decision feedback equalizer can be adapted by using either a least means squared algorithm or a steepest descent algorithm. The gain value of a linear equalizer and the input of a digital to analog converter coupled to the linear equalizer are also adapted through the least means squared algorithm or a steepest descent algorithm. A variable gain amplifier is also capable of being adapted through the use of the least means squared algorithm. Clock offsets are also configured by use of a steepest descent algorithm.
