CODE DIVISION MULTIPLEX COMMUNICATION SYSTEM AND CODE DIVISION MULTIPLEX COMMUNICATION DEVICE

摘要

In a CDMA transmitting apparatus, a cross-correlation value between different spreading-code sequences used to spread respective ones of a plurality of transmit signals is calculated, an interference interval of a spreading-code sequence is discriminated from the cross-correlation value calculated, and interference noise is reduced by halting transmission of at least one transmit signal, or partially altering at least one spreading-code sequence, with regard to all or part of a spreading-code sequence discriminated to be an interference interval.
