Experimental demonstration of bipolar codes for direct detection multi-user optical communication
We report the first experimental demonstration of a broadband spectral encoding and decoding technique using bipolar codes for optical code-division multiple access. The codeword correlations are verified and rejection of ...
Multiuser receivers for code-division multiple-access systems with trellis-based modulation
A code-division multiple-access (CDMA) communication system is studied where a trellis-based scheme is used for data encoding and modulation. The signature sequences (spreading codes), which are assigned to the direct-sequence ...
