SEP Analysis of Quantized SIMO Systems with M-PSK over Correlated Fading Channels
Amila Ravinath, Bikshapathi Gouda, Italo Atzeni +1
The average symbol error probability (SEP) of a phase-quantized single-input multiple-output system with M-ary phase-shift keying modulation and maximum ratio combining (MRC) is an…
SEP Analysis of a Low-Resolution SIMO System with M-PSK over Fading Channels
Amila Ravinath, Minhua Ding, Bikshapathi Gouda +2
In this paper, the average symbol error probability (SEP) of a phase-quantized single-input multiple-output (SIMO) system with M-ary phase-shift keying (PSK) modulation is analyzed…
Over-the-Air Beamforming Design for Full-Duplex Cell-Free Massive MIMO Systems
Bikshapathi Gouda, Antti Tölli
We study a full-duplex (FD) cell-free massive MIMO system where distributed access points (APs) operate in FD mode while user equipments (UEs) remain half-duplex. Although simultan…
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…
