Hybrid MU-MIMO spatial mapping using both explicit sounding and crosstalk tracking in a wireless local area network
摘要
說明書
Different propagation environments may need different sounding intervals for good performance, so it's hard to find a single sounding interval for all environments. A compromise value may be too long for some environments and too short for others. In both cases, this results in a loss in performance compared to an ideal sounding frequency. Instead of sounding at a regular interval, the AP could also use a threshold on the allowed degradation of the original SINR (i.e. relative to the original channel and precoding matrix).
