Uplink Data Detection Analysis of 1-Bit Quantized Massive MIMO

  title={Uplink Data Detection Analysis of 1-Bit Quantized Massive MIMO},
  author={Italo Atzeni and Antti T{\"o}lli},
This paper presents an analytical framework for the data detection in massive multiple-input multiple-output uplink systems with 1-bit analog-to-digital converters (ADCs). Considering the single-user case, we provide closed-form expressions of the expected value and the variance of the estimated symbols when maximum ratio combining is adopted at the base station (BS) along with their asymptotic behavior at high signal-to-noise ratio (SNR). These results are exploited to enhance the performance… Expand
