BER Performance of Spatial Modulation Systems Under a Non-Stationary Massive MIMO Channel Model
In this paper, the bit error rate (BER) performance of spatial modulation (SM) systems is investigated both theoretically and by simulation in a non-stationary Kronecker-based massive multiple-input-multiple-output (MIMO) channel model in multi-user (MU)

An ENZ metamaterial slab enables near‐field coupling suppression in dual circularly polarized stacked patch antennas while preserving radiation performance. The near‐zero‐index environment attenuates the transmission of parasitic coupling components between adjacent radiators, distinct from conventional current‐cancelation or port‐compensation ...

Symbol‐Level GRAND‐Assisted Detection for Polar‐Coded Spatial Modulation in MIMO Systems
This research presents an integrated polar‐coded spatial modulation (PCSM) transceiver scheme for MIMO transmission over Rayleigh fading channels. The proposed architecture employs linear spatial signal processing for antenna and symbol estimation, followed by symbol‐level guessing random additive noise decoding (symbol‐level GRAND)–assisted detection ...
