Abstract
Techniques are disclosed relating to massive MIMO communications. In some embodiments, a base station is configured to dynamically adjust the number of processing elements used for MIMO signal estimation (e.g., the number of MIMO RX chains used for parallel processing). In some embodiments, the number of processing elements may be based on the number of antennas currently being used, the number of spatial streams, interconnect throughput thresholds, sampling rate, etc. In some embodiments, the base station includes configurable MIMO cores configured to dynamically switch between MIMO signal estimation techniques, e.g., on a per-symbol basis. In some embodiments, the base station includes configurable linear decoders configured to separately multiply input matrices and combine or refrain from combining the results based on the number of antennas and/or processing elements currently in use.
