Abstract :
New wavelength/time code families constructed with short code lengths are proposed for optical code-division multiple- access networks. Since the code matrices inherit correlation properties from the underlined one-dimensional codes, much effort for codeword searching and code property validation is saved. In addition, since the proposed code matrices with multipulse-per-row (MPR) property have optimal cardinalities, the total number of supported users in the network is increased. Performance analysis shows that the proposed MPR matrix codes have bit-error rates comparable to other wavelength/time codes proposed previously.
