Abstract
We start with extensions to systems with excess antennas in Sect. 7.1. In the following Sect. 7.2, the feedback methods are extended to frequency selective systems by means of interpolation and clustering, and the lower bound on the Signal to Interference and Noise Ratio (SINR) for Channel Quality Indicator (CQI) feedback is presented in Sect. 7.2.2. The performance of the methods and algorithms is investigated in Sect. 7.2.3 through extensive Monte-Carlo simulations.
