Asymmetric Stream Allocation and Linear Decodability in MIMO Coded Caching
Mohammad NaseriTehrani, MohammadJavad Salehi, Antti Tölli
Coded caching (CC) can transform cache memory at network devices into an active communication resource and significantly enhance the Degrees of Freedom (DoF) of multi-input multi-o…
Low-Subpacketization MIMO Coded Caching with Flexible Stream Allocation
Mohammad NaseriTehrani, MohammadJavad Salehi, Antti Tölli
Subpacketization remains a major obstacle to the practical deployment of coded caching (CC) in multi-antenna wireless networks. In this paper, we propose a low-complexity multiple-…

Mohammad NaseriTehrani, MohammadJavad Salehi, Antti Tölli +1
Integrating coded caching (CC) into multiple-input multiple-output (MIMO) communications significantly enhances the achievable degrees of freedom (DoF). This paper investigates a p…
Cache-Aided MIMO Communications: DoF Analysis and Transmitter Optimization
Mohammad NaseriTehrani, MohammadJavad Salehi, Antti Tölli
Cache-aided MIMO communications aims to jointly exploit both coded caching~(CC) and spatial multiplexing gains to enhance communication efficiency. In this paper, we analyze both t…
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…
Massive MIMO with 1-Bit DACs: Data Detection for Quantized Linear Precoding with Dithering
Amin Radbord, Italo Atzeni, Antti Tölli
To leverage high-frequency bands in 6G wireless systems and beyond, employing massive multiple-input multipleoutput (MIMO) arrays at the transmitter and/or receiver side is crucial…
