Abstract :
In this paper, a practical nonlinear model for high density magnetic recording channels is proposed. Unlike previous Volterra series methods, this model can be constructed based on simple measurements of the isolated transition response and dibit responses. The experimental results show that the proposed nonlinear model accurately predicts the channel output over the entire length of the 1023-bit maximum length pseudo-random binary testing sequence
