A Two-Dimensional Channel Model for Digital Data Storage on Microfilm
Christoph Voges, Tim Fingscheidt · IEEE Transactions on Communications · 2011
Photographic microfilm has become a promising medium for long-term storage of digital data. We present an end-to-end channel model of the whole processing chain including a novel soft-output demodulator for channels with non-Gaussian noise, such as film. The proposed channel model describes the digital microfilm storage channel with good preciseness.
