Energy-Efficient Adaptive MIMO Decoders

Halak, Basel, El-Hajjar, Mohammed, Hu, Qiongda and Lu, Yue (2015) Energy-Efficient Adaptive MIMO Decoders At Science and Information Conference.

Record type: Conference or Workshop Item (Paper)

Abstract

Energy efficiency is a primary design goal of
modern wireless communication systems, especially those
deployed in portable devices such as mobile phones. This paper
presents a novel concept, which allows energy-efficient systems to
exploit the changing nature of their environment in order to save
power. This concept is employed to design an advanced MIMO
decoder, which continuously monitors the signal-to-noise ratio
(SNR) and re-configures its hardware in order to minimize its
energy consumption. The design is implemented in 65nm
technology in order to evaluate its performance and costs. The
results show that the proposed adaptive architecture can achieve
up to 50% of energy consumption savings compared to existing
designs at the cost of an increased area overhead.
