有沒有人了解什麼是minimum coupling loss?
我在網路上找半天越看越迷糊
我遇到的情況大概是這樣
Assume Pathloss' = P(d,theta) 由距離和antenna pattern計算出的loss
and then
Pathloss = max ( Pathloss' , minimum coupling loss)
名符其實的 "minimum loss"
參考值是70dB
但我不了解為什麼會有這樣一個minimum loss
而且又要取成minimum "coupling" loss
---
而跟我在網路上找到的minimum coupling loss method
或是這段定義
MCL is defined as the minimum possible propagation loss between stations of
non-coordinated operators
MCL is defined as the pathloss between a receiving station
(the so-called victim) and its nearest interferer belonging to
another operator in an adjacent frequency band
都有點牛頭不對馬嘴，感覺好像是不一樣的東西@@
