Abstract
This paper proposes higher-order spread spectrum direct optical switching C DMA system and an aliasing canceler to remove the aliasing distortion cause d by higher-order bandpass sampling. Theoretical analysis of the signal qua lity shows that the 3rd order bandpass sampling scheme can improve the carr ier-to-interference-power ratio compared with the conventional Ist order ba ndpass sampling scheme, by 5dB.
