On a multi-antenna broadcast (downlink) channel, simultaneous transmission to multiple users is capable of achieving very high throughput. Unfortunately, the optimal approach for such multi-user transmission, namely dirty paper coding, is highly complicated. Therefore, this paper proposes a practical joint beamforming and scheduling scheme that is enabled by feedback of quantized channel state ...

In order to evaluate the energy distribution (due to matter and fields including gravitation) associated with a space-time model of cylindrically-symmetric Marder universe, we consider the Møller, Einstein, Bergmann-Thomson and Landau-Lifshitz energy and momentum definitions in the teleparallel gravity (TG). The energy-momentum distributions are found to be zero. These results are the same as a...

This paper examines, following an analytical and descriptive methodology, Akram Khan’s approaches towards Biblical sources in his commentary on Qur’an known as Tafsīrsoho Sharif (The Noble with Tafsīr), and, thereby, intends to understand methodology Qur’anic exegesis. Khan denies the acceptance of more than once work. Even he attacks authors narrators who narrated, or allowed them their works ...
