In this paper we consider a multi-user spatial multiplexing (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)
This paper characterizes the performance of cellular networks employing multiple antenna openloop spatial multiplexing techniques. We use a stochastic geometric framework to model distance depended inter cell interference. Using this framework, we analyze the coverage and rate using two linear receivers, namely, partial zero-forcing (PZF) and(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 rates for a cloud radio network using a zero forcing (ZF) equalizer with dirty paper precoding (DPC). We show that when complete channel state information is available at the cloud,(More)
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 top(More)
