Interference with Freedom of Expression

Degrees of Freedom of Interference Networks with Transmitter-Side Caches

This paper studies cache-aided interference networks with arbitrary number of transmitters and receivers, whereby each transmitter has a cache memory of finite size. Each transmitter fills its cache memory from a content library of files in the placement phase. In the subsequent delivery phase, each receiver requests one of the library files, and the transmitters are responsible for delivering ...

Degrees of freedom of wireless interference network

The degrees of freedom (DoF) concept is very useful for studying the multi-user communications system at high signal-to-noise ratio region. The research on DoF leads to an important technology advancement in wireless communications, the interference alignment. The idea of interference alignment is to design the transmit signals structurally such that the interference signals from multiple inter...

Relay-Assisted Interference Channel: Degrees of Freedom

This paper investigates the degrees of freedom of the interference channel in the presence of a dedicated MIMO relay. The relay is used to manage the interference at the receivers. It is assumed that all nodes including the relay have channel state information only for their own links and that the relay has M ≥ K antennas in a K-user network. We pose the question: What is the benefit of exploit...

Democratic Freedom of Expression

This paper suggests the democratic direction in which the right of freedom of expression should be conceived and applied. In the first two sections it suggests some counter-examples to, and diagnoses of, the libertarian and liberal conceptions of freedom of expression, taking Scanlon (1972) and Scanlon (1979), respectively, to be their chief proponents. The paper suggests that these conceptions...
