SEP Analysis of 1-Bit Quantized SIMO Systems with QPSK over Fading Channels
Amila Ravinath, Minhua Ding, Bikshapathi Gouda +2
The average symbol error probability (SEP) of a 1-bit quantized single-input multiple-output (SIMO) system is analyzed under Rayleigh fading channels and quadrature phase-shift key…
Near-Field MIMO Channel Acquisition: Geometry-Aided Feedback and Transmission Design
Shima Eslami, Bikshapathi Gouda, Antti Tölli
Near-field (NF) line-of-sight (LoS) MIMO systems enable efficient channel state information (CSI) acquisition and precoding by exploiting known antenna geometries at both the base…
Uplink Transmit Power Optimization for Distributed Massive MIMO Systems with 1-Bit ADCs
Bikshapathi Gouda, Italo Atzeni, Antti Tölli
This paper addresses the problem of uplink transmit power optimization in distributed massive multiple-input multiple-output systems, where remote radio heads (RRHs) are equipped w…
Pilot-Based Uplink Power Control in Single-UE Massive MIMO Systems With 1-Bit ADCs
Amila Ravinath, Bikshapathi Gouda, Italo Atzeni +1
We propose uplink power control (PC) methods for massive multiple-input multiple-output systems with 1-bit analog-to-digital converters, which are specifically tailored to address…
