On Capacity Performance of 2 × 2 Satellite-earth Link at 30 GHz in Rain Environment

摘要

Give the equivalent model of STBC, VBLAST sche mes for analyzing their channel capacity. The channel capacity performances of SISO, 2×2 STBC and 2×2 VBLAST schemes in 20 mm/h rain environment are simulated and discussed based on an assumed 2×2 satellite-earth link at 30 GHz in circular polarization as an example.
