overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Multiple-Input Multiple-Output (MIMO) systems in satellite links utilize multiple antennas at both the transmitter and receiver to enhance communication performance. By exploiting spatial multiplexing and diversity techniques, MIMO enables higher data throughput, improved link reliability, and better spectral efficiency in satellite communications. This approach is an adaptation of terrestrial MIMO technologies to the unique challenges of satellite channels, such as long propagation delays and variable signal conditions.
