- Abstract :
Novel all-optical parallel implementations of encoder and decoder
systems for error detection and correction with linear codes are
proposed. The key components are optical vector-matrix multipliers and
optical lookup tables. Evaluation is mode of the overall system
throughput and the hardware requirement with a case of a simple
(7,4) Hamming error-detection coding for a two-dimensional picture of
1000 ~ 1000 pixels with near-future ferroelectric liquid-crystal
devices, which results in a best throughput of approximately
5.6 ~ 1010 pixels/s and a size of 1cm~ 1cm with a combination of
time-and space-division techniques.
