In recent years, a two-dimensional (2-D) wavelength-hopping time-spreading (or so-called wavelength-time) coding scheme has been studied for optical code-division multiple-access (O-CDMA) systems in order to support more subscribers and simultaneous users than the conventional one-dimensional approaches. To further improve the numbers of subscribers and simultaneous users in wavelength-time O-CDMA systems without sacrificing performance, a new class of 2-D carrier-hopping prime codes with very good correlation properties and significantly expanded cardinality was recently constructed. In this thesis, the performances of wavelength-time O-CDMA systems utilizing these new 2-D carrier-hopping prime codes are analyzed and compared under chip-synchronous and chip-asynchronous assumptions.
