The 17th Annual IEEE International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC’06) CAPACITY EVALUATION OF VARIOUS MULTIUSER MIMO SCHEMES IN DOWNLINK CELLULAR ENVIRONMENTS
نویسندگان
چکیده
Presented in this paper is a study of the capacity evaluation of various multiuser MIMO schemes in cellular environments. The throughputs per user of the generalized zero-forcing with rank adaptation and vector perturbation schemes are compared with the capacity bound of the Gaussian MIMO broadcast channel, obtained by dirty paper coding under proportional fairness scheduling. The average cell throughputs of these schemes are also compared. From these comparisons, this study provides vital information for applying multiuser MIMO schemes in multicell environments.

This paper describes an outdoor MIMO measurement campaign conducted in the 2GHz band employing a sounding bandwidth of 20MHz. The study aimed to compare the MIMO performance of two prototype devices with a reference dipole antenna module. The results obtained reveal a systematic blocking of one of the PDA antenna ports with the user’s thumb alongside a significant reduction in the available MIM...

Optimised Link State Routing (OLSR) is a popular protocol for use in MANET networks. In this paper, we investigate the different impacts of tuning refresh interval timers on OLSR performance under various scenarios (varying node density and node speed). Based on the simulation results with NS2, we find that although reducing refresh intervals could improve OLSR’s performance, the intervals for ...

In multi-antenna downlink systems the optimization of linear precoding is severely hampered by the amount of feedback. An efficient solution consists in opportunistic schemes, which generate M random beams and schedule the users with the highest signal-to-noise-plus-interference ratios (SINRs), which can be made available to the transmitter with very little feedback. Although this technique has...

We present broadband capacity snapshots as well as grid measurements derived with a fast 5×5 MIMO channelsounder in a typical, large-scale, non-mobile, in-room office scenario where we focus on Line-of-Sight (LOS) transmission channels. The accessible MIMO capacity is compared to its theoretic counterpart which would have been obtained if only the LOS signal without any reflections was consider...

In this paper, a low complexity subcarrier allocation scheme is proposed for multiuser MIMO-multiuser OFDM systems with zero-forcing beamforming (ZFBF) to minimize the total transmit power satisfying given target data rates of users. The ZFBF for multiuser MIMO makes multiple spatial channels by removing multiuser interference and the subcarrier allocation can be performed over spatial and freq...
