Abstract
A system and method including a parity bit encoder for encoding bits of data to be transmitted with first and second parity check bits to produce successive block of bits. Each of the blocks of bits are Gray mapped to a plurality of associated QAM symbols that are modulated onto an optical wavelength and transmitted to a receiver. A de-mapper corrects for 90 degree and 180 degree cycle slip using parity indicated by the first and second parity bits.
