One-Bit Sigma-Delta MIMO Precoding.

Coarsely quantized MIMO signalling methods have gained popularity in the recent developments of massive MIMO as they open up opportunities for massive MIMO implementation using cheap and power-efficient radio-frequency front-ends. This paper presents a new one-bit MIMO precoding approach using spatial Sigma-Delta (ΣΔ) modulation. In previous one-bit MIMO precoding research, one mainly focuses on u...
