Returning to Shannon's Original Meaning
Xuezhi Yang
Shannon theory is revisited to show that ergodicity is an indispensable element of channel capacity. The generalized channel capacity …
Capacity of Fading Channels without Channel Side Information
Xuezhi Yang
There are currently a plurality of capacity theories of fading channels, including the ergodic capacity for fast fading channels and outage capacity for slow fading channels. Howev…
On Non-Orthogonal Multiple Access in Downlink
Xuezhi Yang
Non orthogonal multiple access (NOMA) in the downlink is discussed in this letter. When combined with soft frequency reuse, NOMA is detrimental to user fairness by increasing the d…
On the Capacity Region of Multiple Access Channel
Xuezhi Yang
The capacity region of a multiple access channel is discussed. It was found that orthogonal multiple access and non orthogonal multiple access have the same capacity region under t…
A multi-level soft frequency reuse technique for wireless communication systems
Xuezhi Yang
A multi-level soft frequency reuse (ML-SFR) scheme and a resource allocation methodology are proposed for wireless communication systems in this letter. In the proposed ML-SFR sche…
