MIMO Networks With One-Bit ADCs: Receiver Design and Communication Strategies

High resolution analog to digital converters (ADCs) are conventionally used at the receiver terminals store an accurate representation of received signal, thereby allowing for reliable decoding transmitted messages. However, in a wide range applications, such as communication over millimeter wave and massive multiple-input multiple-output (MIMO) systems, use high ADCs is not feasible due power budget limitations. In conventional fully design, where each antenna connected distinct ADC, reducing ADC leads performance loss terms achievable rates. One proposed method mitigate rate-loss linear combiners leading design hybrid receivers. Here, framework augmented by addition delay elements allow temporal processing. Two new classes receivers consisting elements, combiners, one-bit proposed. The fundamental limits single multi-user (uplink downlink) MIMO systems employing investigated. signal noise ratio regime, it shown that achieve maximum rates among all with same number ADCs.
