— In this paper we propose a transmission concept that combines phase hopping and space-time coding to enable efficient multi-antenna transmission. The proposed space-time code can be considered as a non-orthogonal construction, a sibling of the ABBA code proposed in [7]. The transmission concept proposed here has the advantage that is can be utilized on(More)
—In this paper we consider a multiuser spatial multi-plexing (SM) cellular network, where Nt streams are transmitted to Nt users in the cell. Specifically, we obtain the coverage and rate expressions for a system employing zero-forcing (ZF) receiver. Compared to single stream transmission (SST), it is interesting to see that SM degrades the rate for a(More)
Cooperation in a cellular network is seen as a key technique in managing other cell interference to observe a gain in achievable rate. In this paper, we present the achievable rate regions for a cloud radio network using a sub-optimal zero forcing equalizer with dirty paper precoding. We show that when complete channel state information is available at the(More)
