Abstract

We consider multiple input multiple output, orthogonal frequency division multiplexing, code division multiplexing (MIMO-OFDM-CDM) techniques for the efficient improvement of the link reliability/spectral efficiency of very high data rate communication systems. In particular, we apply MIMO detection methods based on lattice reduction, partial decision feedback (PDF), and BLAST ordering techniques to MIMO-OFDM-CDM systems. Simulation results show that the proposed receivers significantly outperform the conventional zero-forcing (ZF), minimum mean squared error (MMSE), and vertical Bell Labs layered space time (V-BLAST) receivers without severely compromising system complexity.
