Upcoming
Events Extending the Dorsch Decoder for Efficient Soft Decision
Decoding of Linear Block Codes Speaker: Sean Collison The research presented builds upon a
method of decoding linear block codes presented by Dorsch in 1974. An
algorithm is presented that details how to extend the Dorsch Decoding
method to check error patterns in the most likely order that they
occur. Furthermore, another method is described that increases
decoding speed by using various stopping criteria to limit the depth
of the error pattern search. Multiple codes of various rates are
investigated to find the best performing code subject to a
decoding complexity constraint. Sean Collison is an IEEE Member and the current
Treasurer for the Boise Section. Sean has been a Firmware
Design Engineer at Hewlett Packard from June 2010 to present.
He currently works in HP’s Value Enterprise Products group on
enterprise LaserJet printers and copiers. Prior to joining HP,
he was a Sr. Graduate Intern at Comtech AHA, in Tuesday,
