The system capacity is increased by increasing the highest number of users in one time slot. The additional channel estimation processing required for the increasing number of users is solved by adopting the reduced-rank technique, which estimates a limited number of parameters that are needed to describe the channel matrix and reduce the dimensionality of this matrix. Simulation results prove the validity of the proposed reduced-rank technique for channel estimation accuracy enhancing. Additionally, it is shown that the detectors based on the reduced-rank estimators outperform traditional channel estimators, contributing to 7.8 and 6.9 dB BER performance improvements for indoor and vehicular channels, respectively. 2014-05-05T09:12:14Z 2014-05-05T09:12:14Z 2013-02 Article Circuits, Systems, and Signal Processing, vol. 32(1), 2013, pages 205-221 0278-081X http://link.springer.com/article/10.1007%2Fs00034-012-9443-9 http://dspace.unimap.edu.my:80/dspace/handle/123456789/34265 en Springer Science+Business Media, LLC |
