Massive MIMO arrays are envisaged for 5G and beyond deployment due to the colossal gains in spectral efficiency. Existing implementations, however, involve tens of RF chains to support massive MIMO transmission, and hence a prohibitive hardware complexity.
Since the gain in spectrum efficiency from massive MIMO deployment translates into increased capacity, a mobile operator which for instance has 20 million subscribers could support an additional 5 million subscribers using ESPAR-based massive MIMO deployment without additional spectrum costs, hence increasing profit margins.
The benefits of ESPAR transmission extend beyond massive MIMO, and they can find benefits in hardware-/power-efficient access points, deployment in drone communications, and other yet-to-be-explored applications.
