Multi-Antenna Multi-User Communication (Gaussian Vector Broadcast Channel) Projects scope: - Analyze the sensitivity of capacity of multi-user multi-antenna wireless communication system versus the number of users being served. - Analyze and improve the vector perturbation technique. - Design precoding matrix. - Investigate the amount of CSI needed to approach capacity of such channel.
