On a class of time varying shapers with application to the renegotiable variable bit rate service
A shaper is a system that stores incoming bits in a bu er and delivers them as early as possible, while forcing the output to be constrained with a given arrival curve. A shaper i...

Transceiver optimization for multi-user multi-antenna two-way relay channels
In this paper, we study a multi-user multi-antenna two-way relay system, where a multi-antenna base station (BS) exchanges uplink and downlink signals with multiple users via a mu...
