Abstract
An improved error code correction algorithm for phase-shifted optical quantisation is presented and experimentally demonstrated. The error probabilities for each valid code are calculated and the invalid codes are corrected by using the maximum likelihood estimation algorithm. The experimental result shows that the spur-free dynamic range of the system has an improvement of 2.28 dB compared to the Hamming algorithm in a 10-GSamples/s, 4-bit resolution all-optical analogue-to-digital converter.
