Abstract:
1. An optical system comprising: a digital signal processor (DSP) configured to: receive first samples of a digital signal, correlate the first samples to a plurality of groups of second samples to determine a plurality of correlation values, determine a particular code word, of the plurality of code words, corresponding to one of the correlation values of the plurality of correlation values, determine output bits based on bits of the particular code word and the one of the correlation values, and provide the output bits, a local oscillator configured to provide a reference optical signal; a hybrid mixer configured to: a photodetector configured to: an analog-to-digital converter (ADC) configured to: where when receiving the samples of the digital signal, the DSP is further configured to receive the samples of the digital signal based on the digital signal provided by the ADC.
