This paper focuses on channel estimation in singleuser and multi-user MIMO systems with multi-antenna base stations equipped with 1-bit spatial sigma-delta analog-to-digital converters (ADCs). A careful selection of the quantization voltage level and phase shift used in the feedback loop of 1-bit sigmadelta ADCs is critical to improve its effective resolution. We first develop a quantization noise model for 1-bit spatial sigmadelta ADCs. Using the developed noise model, we then present a two… Expand

This paper proposes a channel estimation algorithm for a narrowband single-user mmWave line-of-sight MIMO system by determining the unknown angles and path attenuation that characterize the flat-fading channel and demonstrates that the performance of the developed method is comparable to the traditional unquantized system and significantly better than the conventional 1-bit quantized system.
