Abstract

Two wideband physical-layer multiple access techniques for mobile telephony and data are compared: CDMA, which in one of several manifestations has been chosen for virtually all third generation cellular systems, and OFDM with MIMO, which seems to be the most favored for a future generation. We compare the Shannon capacities of the two and conclude that with appropriate processing CDMA and OFDM capacities are similar but that the latter may more effectively be combined with MIMO antennas to provide higher capacities.
