MULTI-WAVELENGTH OPTICAL CDMA WITH DIFFERENTIAL ENCODING AND BIPOLAR DIFFERENTIAL DETECTION

摘要

The present invention relates generally to an optical CDMA transmission system and method employing differential optical encoding and bipolar decoding. Differential encoding and bipolar decoding may be performed at the bit level, wherein differential phase encoding and decoding occurs on an entire composite signal. Differential encoding and bipolar decoding may also be performed at the chip level, wherein differential phase encoding and decoding occurs on individual spectral components of a given signal.
