Abstract :
This paper proposes adaptation algorithms for adapting a class of practical continuous time equalizer architectures. Gradient equations used to adapt the equalizer are derived based on impulse response weights related to the equalizer. A simplified version of the gradient is proposed. Simulation results across a range of real backplane channels show proper convergence of the gradients and minimal performance loss for the simplified gradient.
