Code sequence generator in a CDMA modem

摘要: A CDMA modem includes a transmitter having: code generator which provides an associated pilot signal and generates plurality of message signals: spreading circuit produces spread-spectrum by combining each the information signals with respective one signals; global that to are synchronized. The also receiver having group correlators for correlating code-phase delayed versions receive CDM produce despread signal. phase is changed responsive acquisition value until received. tracking logic adjusts in so power level maximized. Finally, circuits, including correlate local received
