摘要: An apparatus for controlling handoff in a spread-spectrum-CDMA-communications system, of radio devices moving from cell having base station which transmits first spread-spectrum-communications signal with generic-chip-code signal, toward different transmitting second signal. A device includes PCN antenna, matched filter an impulse response to the and detector detecting embedded has detects comparator generates comparison by comparing detected receiver-message-chip-code generator replica message-chip-code message mixer, using despreads as modulated-data synchronization circuit, based on being greater than threshold, synchronizes receiving less control unit switches data, spread-spectrum processed station, transmitted station.
