论文摘要
本文着重于具有1位空间Sigma-Delta类似物到数字转换器（ADC）的MMWave MIMO系统的通道估计。具有1位空间Sigma-Delta ADC的通道估计性能取决于量化噪声模型。因此，我们提出了一种通过利用1位空间Sigma-Delta ADC的确定性输入输出关系来建模量化噪声的新方法。使用这种新的噪声模型，我们提出了一种算法，用于通过确定表征扁平褪色通道的未知角度和路径衰减，来进行窄带单用户MMWAVE MMWAVE MMWAVE MIMO系统的频道估计。通过模拟，我们证明了开发方法的性能与传统的模拟系统相当，并且明显优于传统的1位量化系统。
This paper focuses on channel estimation for mmWave MIMO systems with 1-bit spatial sigma-delta analog-to-digital converters (ADCs). The channel estimation performance with 1-bit spatial sigma-delta ADCs depends on the quantization noise modeling. Therefore, we present a new method for modeling the quantization noise by leveraging the deterministic input-output relation of the 1-bit spatial sigma-delta ADC. Using this new noise model, we propose an algorithm for channel estimation 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. Through simulations, we demonstrate that the performance of the developed method is comparable to the traditional analog systems and significantly better than the conventional 1-bit quantized systems.
