Enhanced Uplink Data Detection in Massive MIMO with 1-Bit ADCs: Analysis and Joint Detection

We present a new analytical framework for the uplink data detection in massive multiple-input multiple-output systems with 1-bit analog-to-digital converters (ADCs). We first characterize the expected values of the soft-estimated symbols (after the linear receiver and prior to the data detection), which are affected by 1-bit quantization during both the channel estimation and the uplink data transmission. In our analysis, we consider conventional receivers such as maximum ratio combining (MRC),
