Claims (9)
- 통신 시스템 내 수신기에서 취득 표시기 비트(AIs)를 결정하는 방법에 있어서, 상기 방법은,다중화된 취득 비트 y=B × AI + n을 수신하는 단계로서, B는 기지국과 수신기에 알려진 시그니쳐 매트릭스이고, AI는 모든 취득 표시기 비트이며, n은 노이즈를 나타내는, 상기 수신 단계와;취득 표시기 비트(AIs)를로 설정하는 단계로서, R과 U는 결정 임계값인, 상기 설정 단계를 포함하되,에 의해 계산되고,J는 0보다 크거나 같은 정수인 것을 특징으로 하는 취득 표시기 비트 결정하는 방법.
- 제 1 항에 있어서,R과 U는 절대값이 동일한 것을 특징으로 하는 취득 표시기 비트 결정하는 방법.
- 제 1 항에 있어서,R과 U는 각각 -0.5와 0.5인 것을 특징으로 하는 취득 표시기 비트 결정하는 방법.
- 제 1 항에 있어서,상기 방법은 매트릭스 B 또는 BT를 사전 저장하는 것을 특징으로 하는 취득 표시기 비트 결정하는 방법.
- 제 1 항에 있어서,상기 방법은 소프트웨어에서 수행되는 것을 특징으로 하는 취득 표시기 비트 결정하는 방법.
