Abstract

We propose an efficient multiple-input multiple-output concept based on space-time turbo coded modulation and layered spatial multiplexing architectures for cellular multicarrier code-division multiple access systems. We design appropriate receiver algorithms, and compare their performance to competing schemes in a single-cell system. We then evaluate the performance of the scheme in a seven-cell system with universal frequency reuse. The proposed MIMO scheme improves throughput significantly compared to the corresponding single-antenna communications even in the presence of spatial correlation.

Funding

This research was supported by the National Technology Agency (TEKES) of Finland, Nokia, the Finnish Defense Forces, Elektrobit, and Instrumentointi. Parts of this article were presented at IEEE ICC 2004, Paris, France, June 20–24, 2004 (its longer and more detailed version has been submitted to IEEE Transactions on Vehicular Technology), and some parts were presented at the 2004 Nordic Radio Symposium, Oulu, Finland, August 16–18, 2004. Those papers include the detailed mathematical derivations and analysis of the proposed techniques as well as related results, but not the same result illustrations as this submission. Another related paper by the authors will appear in IEICE Transactions on Communications later this year (and its conference version appeared at PIMRC 2004, Barcelona, Spain September 5–8, 2004). However, the receivers applied therein are different from those in this submission. Furthermore, none of the earlier publications holds the tutorial nature of this submission.
