In the case of unbalanced configurations (more transmit than receive antennas), we demonstrated that chip-level combining clearly outperforms symbol-level combining.
As radio-based wireless becomes ubiquitous, more and more devices transmitting more and more data are able to connect to the internet, either through the mobile-phone network or through Wi-Fi.
In general, she said, hepatitis A and B outbreaks are more common, because they are more easily transmitted.
Locally adapted pathogens are more readily transmitted among and can be more virulent to genetically similar hosts [ 3].
Effectively, more transmit antennas mean that the transmit vectors are spread in a larger Euclidean space.
On one hand, the gain comes from the diversity order brought by more transmit antennas.
For one thing, more transmit antennas would increase the spatial multiplexing and diversity gain that leads to transmit power saving, while more transmit antennas would increase "Dyn-I" and "Dyn-III" leading to dynamic power wasting.
When the relay is close to one of the sources, more transmit power can be saved with the proposed algorithm.
For the DSM, in order to increase the spectral efficiency, more transmit antennas need to be used.
