Classification: CPC H | IPC H

Claim 9:
10. A method for an optical transmitter comprising:
generating first codewords by encoding data using a staircase code;
spreading a transmission order of the first codewords by interleaving the first codewords using convolutional interleaving, the convolutional interleaving comprising outputting blocks of a predetermined number of consecutive bits from the first codewords in a sequence that spreads burst errors across the first codewords generated using the staircase code;
generating second codewords by encoding the interleaved first codewords using a second code;
mapping the second codewords to transmit symbols;
distributing the transmit symbols between pilot symbols by interleaving the transmit symbols;
generating a transmit frame including the interleaved transmit symbols and the pilot symbols; and
transmitting the generated transmit frame from the optical transmitter to a receiver over a communication channel.
