    • The present invention relates to a receiver for processing a received signal (SEQ), said receiver being multimode. The invention is characterized in that it comprises; a) a single RF chip for processing the received signal (SEQ) in any mode, said chip comprising a spreading section (SPREAD SEC) for spreading and downconverting to baseband a received signal (SEQ), and a channel filtering section (CH SEC) for DC offsets rejection on a received signal (SEQ), and b) a single baseband chip (BB) comprising despreading means (DSPR) for despreading a spread signal (SEQ).
    • 本发明涉及一种用于处理接收信号(SEQ)的接收机,所述接收机是多模式的。 本发明的特征在于它包括: a)用于以任何模式处理所述接收信号(SEQ)的单个RF芯片,所述芯片包括用于扩展和下变频到接收信号(SEQ)的基带的扩展部分(SPREAD SEC)以及信道滤波部分(CH SEC) 用于对接收信号(SEQ)进行DC偏移抑制,以及b)包括解扩展扩展信号(SEQ)的解扩装置(DSPR)的单基带芯片(BB)。
