Abstract :
This paper introduces a novel merger of OFDM systems, MIMO systems, and carrier interferometry (CI) spreading codes. Specifically, previous works have illustrated the performance benefits of (1) applying CI spreading codes to OFDM and (2) merging MIMO and OFDM systems. In this paper, OFDM systems are combined with both a MIMO system and CI spreading codes, resulting in the so-called MIMO-CI/OFDM system, capable of very reliable communication at SNRs previously possible only with channel coding.
