Joint User Identification and Channel Estimation Over Rician Fading Channels
Liang Wu, Zaichen Zhang, Jian Dang +3
This paper considers crowded massive multiple input multiple output (MIMO) communications over a Rician fading channel, where the number of users is much greater than the number of…
Transmission Schemes for Four-Way Relaying in Wireless Cellular Systems
Huaping Liu, Petar Popovski, Elisabeth de Carvalho +3
Two-way relaying in wireless systems has initiated a large research effort during the past few years. While one-way relay with a single data flow introduces loss in spectral effici…
Sum-Rate Optimization in a Two-Way Relay Network with Buffering
Huaping Liu, Petar Popovski, Elisabeth de Carvalho +1
A Relay Station (RS) uses a buffer to store and process the received data packets before forwarding them. Recently, the buffer has been exploited in one-way relaying to opportunist…
