Massive MIMO with 1-bit ADC

Understand

We investigate massive multiple-input-multiple output (MIMO) uplink systems with 1-bit analog-to-digital converters (ADCs) on each receiver antenna.

• Receivers that rely on 1-bit ADC do not need energy-consuming interfaces such as automatic gain control (AGC).
• This decreases both ADC building and operational costs.
• Our design is based on maximal ratio combining (MRC), zero-forcing (ZF), and least squares (LS) detection, taking into account the effects of the 1-bit ADC on channel estimation.
