Abstract
A cordless telephone system including a master phone connected to a telephone line and a slave phone executing communication via one of a plurality of radio channels switchable to said master phone, the master phone and slave phone each having a correlation detector for detecting a correlation value between a received signal and a reference spreading code series, a comparator for comparing the correlation valued detected by the comparator to a prespecified reference correlation value, and a control circuit continuing communication by switching a radio channel when it is determined that the correlation value is lower than the prespecified reference value.
