Extremely Large Aperture Massive MIMO: Low Complexity Receiver Architectures
Extremely Large Aperture Massive MIMO: Low Complexity Receiver Architectures
This paper focuses on new communication paradigms arising in massive multiple-input-multiple-output systems where the antenna array at the base station is of extremely large dimension (xMaMIMO). Due to the extreme dimension of the array, xMaMIMO is characterized by spatial non-stationary field properties along the array; this calls for a multi-antenna …
