Abstract:
Hybrid precoding design for adaptive sub-connected arrays offers a compromise between hardware complexity and spectral efficiency in massive multiple-input multiple-output (MIMO) systems at millimeter wave (mmWave) frequencies. This paper focuses on the impacts of the partially antenna connections on the achievable sum-rate performance in mmWave networks. The subarray architectures consist of the overlapped, interlaced, and dynamically selective subset schemes. Finally, simulation results demonstrate that a dynamic pre-defined set subarray architecture in conjunction is able to accomplish the ASR performance approaching the fully-connected architecture with an alleviated demand on hardware complexities.
