Abstract
With the development of multiple-input multiple-output (MIMO) techniques, distributed antenna systems gain more attention because of better signal coverage than centralized antenna systems. However, hardware costs and computational complexity appear to be a big problem with the growth in the number of antennas in distributed antenna systems as well. Research on antenna selection performance is conducted on indoor distributed antenna systems environment in order to solve the above problem. An antenna selection algorithm based on eigenvalues is proposed. Simulation results show that the algorithm cannot only achieve good antenna selection performance, but also has a much reduced computational cost.
