Indoor Antenna System and Method of Operation

An indoor antenna system comprises one or more antenna modules. Each antenna module including an antenna array configured to receive an input signal and generate a plurality of outputs, a selector that selects a subset of the plurality of outputs, and a converter that converts the subset of the plurality of outputs into a set of digital streams. The antenna system further includes a processor that receives and analyzes outputs from the one or more antenna modules and generate an output signal corresponding to the input signal, and a controller that controls states of the one or more antenna modules. Each antenna module is configurable to be in any of a plurality of states to receive the incoming signal. The controller is configured to cause the state of each antenna module to change extremely fast so that each state lasts for a time corresponding to a few wavelengths, long enough so at least one wavelength is observed at a particular state. The processor is configured to obtain maximum achievable SINR for the output signal from digital streams output from the one or more antenna modules at various states.
