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…
Coordinated Multi-BS SSB Beam Design for Enhanced Initial Access Coverage
Hakime BarghiZanjani, Bikshapathi Gouda, Antti Tölli
Ensuring strong synchronization signal block (SSB) coverage is essential for reliable user equipment (UE) connection during initial access. While techniques such as power boosting…
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…
Data-Aided Regularization of Direct-Estimate Combiner in Distributed MIMO Systems
Bikshapathi Gouda, Italo Atzeni, Antti Tölli
This paper explores the data-aided regularization of the direct-estimate combiner in the uplink of a distributed multiple-input multiple-output system. The network-wide combiner ca…
