Description
信号条件データが、例えば、電力レベル命令履歴(電力上昇/電力下降)、移動端末により受信されたACK/NACK信号、システム負荷指示子(すなわち、RAB)、チャンネル品質指示子(すなわち、DRCロック)、これらの結合及びこれらと類似なものを含むことができることを想起しよう。
次の動作は、4つの電力制御命令をグルーピングし、その後、(上昇、上昇、上昇、上昇)または(下降、下降、下降、下降)のような電力制御命令の4個の連続した発生の個数を数えることを提供する。
他の動作は、例えば、数学式1を用いて遷移確率行列を計算することを含む。
α=1である、または、小さい。
α=0である、または、大きい。
前記関数は、本の例として、次のような指数関数でありうる。
ここで、Uは単位階段関数である。
