In wireless edge caching, it is usual to cache the contents likely to be requested. Contrary to
this traditional approach, we show that under heterogeneous content preference, caching …

This paper proposes an interference suppression scheme based on linear combining for
multiple relay systems. Interference from base stations and relays in neighboring cells …

To cope with the interference problem in three-cell wireless relay systems, this paper
proposes two schemes that perform interference suppression and multiuser detection. The …

To cope with interference in three-cell multiple relay systems, this paper proposes schemes
that detect two users' signals while linearly suppressing one remaining user's signal. The …

In two-cell scenarios with half-duplex relays, the number of diversity branches provided by
the relays is sufficient to suppress one interfering signal. However, the same diversity …

The demand for high data rate wireless services has grown tremendously. The demand is
expected to grow further at an increased pace. The scarcity of the usable radio frequency …

The outage probability of a two-hop coordinated decode-and-forward relay network is
investigated. Relay coordination is performed only with the dominant interferer. Different …

To suppress intercell interference for three-cell half-duplex relay systems, joint interference
suppression and multiuser detection (MUD) schemes that estimate weight coefficients by the …
