Codebook-Based Effective CSI Feedback for Precoding Design in MIMO Systems
Bikshapathi Gouda, Antti Arvola, Juha Karjalainen +2
Downlink multi-user multiple-input multiple-output (MIMO) precoding with limited channel state information (CSI) feedback in multi-cell systems is studied. Conventional codebook-ba…
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 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…
