Abstract
A general scheme called orthogonal frequency CDMA (OFCDMA) to describe CDMA using orthogonal carriers is proposed. Three well-known multicarrier CDMA schemes can be derived as special cases of the proposed OFCDMA if we appropriately define the signature waveforms and separation between adjacent carriers. We proceed with a unified analysis of OFCDMA to systematically understand the performance of these three schemes. Five types of interference can exist in a OFCDMA system under a multi-ray multipath fading channel. We compare the three schemes for each type of interference and discuss their pros and cons to help in designing effective OFCDMA receivers in interference-limited environments.
