Description
式中、cは出力符号語、mは入力ベクトル、Gは生成行列である。
次いで、生成行列Gは、次のように生成される。biに対応するGの行(すなわち行i+1)は、mi1で充当され、エントリの残りは、0である。したがって、入力ビットは、次第に少なくなるパリティ検査に関与し、それゆえ、次第に少なくなる誤り保護を受ける。
式中、mCQIはCQIビット、mAckは家訓応答情報、Gは生成行列である。例えば、mCQIは1×5行ベクトル、mAckは単一ストリームについて1ビット(一般に、m個のストリームでは1×m行ベクトル)、Gは、6×30行列であり、最後の行における最初の20個の要素が0である。
