  •  

    RSError correcting codes (convolutional codes, block codes, Turbo codes, LDPC codes, etc.) play an essential role in modern digital high data-rate transmission systems. They are part of almost every modern communication and storage/recording device, like your CD player, your DSL home Internet access, and your mobile phone, to name just a few.

    This course will focus on theory, construction, and algorithms for error correcting codes, and will highlight the application in communication systems. For modern communications, coding knowledge is a must.
