—This paper introduces the principles of interferom-etry to multicarrier code division multiple access (MC-CDMA). 1 additional users with pseudo orthogonal positioning. When compared to MC-CDMA schemes capable of supporting greater than users, CI/MC-CDMAs performance exceeds that of MC-CDMA. Additionally, this new system is analyzed in the presence of phase(More)
| In this letter, a procedure for generating N Rayleigh fading envelopes with any desired c ovariance m a-trix is given. This method, numerical in nature, enables researchers to simulate correlated fading envelopes, for use in: (1) the study of the impact of correlation on diversity system performance and (2) the study of Multi-Carrier CDMA (MC-CDMA), where(More)
In this letter, a large set of spreading codes that doubles capacity in multicarrier code-division multiple-access (MC-CDMA) systems without any cost in bandwidth and with negligible cost in performance is introduced. This large set is comprised of: 1) complex spreading codes instead of conventional real-valued spreading codes and 2) two sets, each made up(More)
This work summarizes the current state of the art in software radio for 4G systems. Specifically, this work demonstrates that classic radio structures, e.g., heterodyne reception, homodyne reception, and their improved implementations, are inadequate selections for multi-mode reception. This opens the door to software defined radio, a novel reception(More)
