Performance analysis of polar coded MIMO antenna system over Rayleigh fading channel

The Multiple Input -Multiple Output (MIMO) technology employs several antennas at both the transmitter and receiver ends.These systems may attain diversity gain, mitigating fading effects, while multiplexing gain enhances the data transfer rate.Examining polar codes (PC) in fading fading channels (RFC) has significant implications for using PC in wireless communications.The combined detection and decoding (CDD) approach based on turbo codes is computationally intricate and lacks robustness.So, a Polar coded Multiple Input Multiple Output Antenna System (PC-MIMO-AS) has been suggested for operation over an RFC to enhance resilience and diminish complexity.In the course of signal evaluation and recognition, PC has been examined to improve resilience by transforming the restrictions of Galois field (GF) codes into an agile signal system.Also, PC has been included to promote spectrum efficiency and computational effectiveness for CDD in MIMO-AS.The effectiveness of the proposed PC-MIMO-AS method is evaluated under diverse simulation conditions.This study simulates MIMO-AS using four antenna configurations: (2x1), (2x2), (2x3), and (2x4), all using Alamouti's Space Time Block Codes (STBC).The antenna designs were further tested using two modulation schemes: 16-Quadrature Amplitude Modulation (16-QAM) and 64-QAM.
