Abstract:
1. A method of transmitting data in an optical packet network, the method comprising: encoding via a node in the optical packet network groups of K payload bits into N bit blocks of coded payload data using complimentary constant-weight code (CCWC), wherein the CCWC has 2 in parallel with the encoding step, exclusively OR'ing information from a label message with a signature sequence to produce chip data; exclusively OR'ing each group of B blocks of N bits of the coded payload data with one chip of the chip data to produce a portion of coded composite packet data in which each B block in the group of B blocks of N bits has an average power equal to W/N when the one chip is a first chip type and (N−W)/N when the one chip is a second chip type; and generating an optical signal of a particular wavelength that corresponds to the coded composite packet data.
