Abstract
A method () of transmitting digital information via a nonlinear optical channel (), comprises receiving () data () comprising at least a portion of the digital information. A plurality of frequency domain symbols is generated () from the data, and each symbol is assigned to one of a predetermined plural number of frequency sub-bands. Each sub-band may be processed separately () to reduce a peak-to-average power ratio (PAPR) of a transmitted optical signal. The optical signal () is then generated () comprising the plural number of sub-bands, and transmitted via the nonlinear optical channel (). The plural number of frequency sub-bands is predetermined so as to reduce nonlinear optical distortion of the optical signal within the nonlinear optical channel relative to a corresponding single frequency band signal. A corresponding information-receiving method, a transmitter apparatus and a receiver apparatus are also disclosed.
