SISO and MIMO FSO based links under different weather conditions: system evaluation

Shrouk M. Moustafa et al.

Summary: This paper investigates the performance of point-to-point optical wireless communication using Free Space Optics (FSO) systems under different weather conditions. Through analyzing different modulation schemes, it is found that in MIMO systems, the received signal power of CSNRZ and DBNRZ is improved by 21%, MDBNRZ increases by approximately 22%, and OOK-NRZ is enhanced by 23% in SISO systems and 25% in MIMO systems compared to literature.

SDR Implementation of a Real-Time Testbed for Spectrum Sensing Under MIMO Time-Selective Channels for Cognitive Radio Applications

Hayfa Ben Thameur et al.

Summary: This letter discusses experimental studies of spectrum sensing function in high-mobile wireless communication environments using cognitive radio technology. By applying SS function to time-selective multiple-input-multiple-output channels through software-defined radio platform, it was found that proper selection of SS algorithm can enhance communication system performance, such as increasing receiver velocity, reducing sensing time, and improving detection capability.
