Dropping Users in a Multi-Antenna Broadcast Channel
We analyze the sensitivity of the capacity of a multi-antenna multi-user system to the number of users being served simultaneously. We show analytically that the capacity loss of serving fewer users at low SNR is much smaller than at high SNR. The advantages of serving fewer users are many: multi-user algorithms often have better performance, lower complexity, and reduced channel-knowledge requ...
متن کاملOn Achivable Rates in a Multi-Antenna Gaussian Broadcast Channel
| A Gaussian broadcast channel with r single-antenna receivers and t antennas at the transmitter is considered. Both transmitter and receivers have perfect knowledge of the channel. Despite apparent simplicity, this model is in general a non-degraded broadcast channel, for which the capacity region is not fully known. We propose a novel transmission scheme based on \ranked known interference" (...
متن کاملHow many scientific papers should be retracted?
In European research today, mobility has become firmly entrenched as a pre requisite for a successful scientific career; however, the reasons behind this emphasis on scientific nomadism are far from obvious. It is all too common for science policy-makers and funding bodies to extol the seemingly endless virtues of mobility, but it nearly amounts to heresy to ponder the possibility that a move a...
متن کاملHow Many Bins Should Be Put in a Regular Histogram
Given an n-sample from some unknown density f on [0, 1], it is easy to construct an histogram of the data based on some given partition of [0, 1], but not so much is known about an optimal choice of the partition, especially when the set of data is not large, even if one restricts to partitions into intervals of equal length. Existing methods are either rules of thumbs or based on asymptotic co...
متن کاملHow should Rural Women's Enterprises Be Developed and Promoted?
This study was a qualitative research which was done by a case study approach. The samples were chosen from rural development experts of Hamedan Province during a snowball sampling process. The data were collected by the semistructured interviews. The data collection was done by faceto- face interviews, after the interview questions guide was determined. The theoretical saturation was attained ...
