Schedule for this course

The industry's first "hands-on" PRML course - where theory meets practice - is designed to build intuition for solving real world PRML channel problems. This course provides a deep understanding of the practice of PRML and gives students exposure to sophisticated, professional tools they can use on the job to better understand, test, evaluate, compare and optimize read channels.

Managers, engineers and technicians will get hands-on experience using ChannelScience's software package, PRMLpro^TM to experiment with major functions of the read channel. During the class, students use this PC-based model to create realistic waveforms, apply noise and distortion, find errors made by the Viterbi detector and then, best of all, learn how to change channel parameters to improve the detector's performance. The section on LMS adaptation of FIR filters and noise coloration are especially popular. Every student receives a CD with a one-year license to the software tool PRMLpro^TM Student Edition, to use back on the job. Students are encouraged to bring their own ASCII waveform files to try with PRMLpro^TM after class.

This course is the perfect complement to KnowledgeTek's Noise-Predictive PRML Channels for Data Storage class, which is a recommended prerequisite for Hands-On PRML.
