Description
本実施の形態に係る基地局100の構成を図5に示し、本実施の形態に係る移動局200の構成を図6に示す。
図11に示すように、W#0が(1,1,1,1)、W#1が(1,−1,1,−1)である場合、W#0とW#1とは前半の2チップ同士で直交するとともに、後半の2チップ同士で直交する。同様に、W#2が(1,1,−1,−1)、W#3が(1,−1,−1,1)である場合、W#2とW#3とは前半の2チップ同士で直交するとともに、後半の2チップ同士で直交する。よって、2シンボル時間の間の伝搬路状態の変化が十分小さければ、W#0とW#1との間の符号間干渉、および、W#2とW#3との間の符号間干渉は発生しない。よって、W#0および#W1を用いた2次拡散によりコード多重された複数の応答信号を前半の2チップと後半の2チップとに分けて分離することができる。同様に、W#2および#W3を用いた2次拡散によりコード多重された複数の応答信号を前半の2チップと後半の2チップとに分けて分離することができる。
ZC系列を用いた1次拡散によるコード多重、すなわち、循環シフト軸上でのコード多重では、上記のように、ZC系列間での符号間干渉が発生しない程度の十分な循環シフト量の差をZC系列間に設けている。よって、ZC系列間の直交性は崩れにくい。また、高速移動する移動局が存在する場合でもZC系列間の直交性が崩れることはない。一方、ウォルシュ系列を用いた2次拡散によるコード多重、すなわち、ウォルシュ軸上でのコード多重では、上記のように、高速移動する移動局が存在する場合にウォルシュ系列間の直交性が崩れやすい。よって、2次拡散により応答信号をコード多重する場合には、直交性が崩れにくい循環シフト軸上での平均多重度を増加させ、直交性が崩れやすいウォルシュ軸上での平均多重度を減少させることがよい。また、一部のZC系列で1次拡散された応答信号のみにおいてウォルシュ軸上での多重度が極端に大きくなることがないように、ZC系列間において、ウォルシュ軸上の多重度を均一に(一様に)させることがよい。つまり、応答信号を循環シフト軸上およびウォルシュ軸上の双方で2次元拡散する場合には、ウォルシュ軸上での平均多重度を減少させつつ、ウォルシュ軸上の多重度をZC系列間において均一に(一様に)させることがよい。
