As we move towards densified networks for mobile access, with a larger number of access points, the need for high performance wireless backhaul increases drastically. In this respect, line-of-sight (LoS) multiple-input, multiple-output (MIMO) communication is a promising technique which can enable spatial diversity gains in such links, without increasing the allocated bandwith or overstepping requirements...
Practical MIMO communication systems suffer performance loss from oscillator phase noise. In particular, if maximum likelihood (ML) detection is performed naively without considering the phase noise, it results in an error floor in its symbol error probability. In this paper, we propose a method to detect the correctness of the naive ML solution in the presence of strong phase noise. A criteria based...
In wireless cooperative systems, the outage probability is a relevant performance measure from the information theoretic point of view. Deriving its exact value with respect to the relaying protocol parameters and for all the range of the Signal to Noise Ratio is in general a hard task. Instead, one can extract the outage gain in order to approximate the outage probability as the SNR goes to infinity...
The flip-and-forward scheme introduced in (Yang-Belfiore, 2007) for handling communication in multi-hop MIMO relay networks was shown to achieve a better diversity-multiplexing tradeoff than pure amplify-and-forward schemes. In the present paper, we show that the flip-and-forward scheme actually achieves the optimal diversity-multiplexing tradeoff for a two-hop relay network, when the relay is equipped...
