Adaptive beamforming using distributed antenna Arrays: Joint versus distributed processing

This work presents our analysis on adaptive beamforming and combining techniques applied to a system consisting of distributed antenna arrays. Our analysis reveals the connection between the theoretical and the practical schemes for data combination. The important roles played by the canonical correlations (CC), which may or may not exist among multiple data sets in a distributed antenna system, are studied to justify the use of different combining techniques for different operation environments.
