发明名称 Spread-spectrum phase and channel tracking
摘要 Common components are used to detect messages from a variety of transmitters, and the characteristics of each detected message are used to dynamically configure the demodulation process for each message. Channelization is selectively performed before, after, or before-and-after de-spreading, depending upon the particular environment and/or the particular characteristics of the received messages. Frequency synchronization to each transmitter is achieved by initializing a tracking loop within the demodulator associated with the transmitter, and code-phase synchronization to each transmitter is achieved by selectively inserting or deleting bits, based on the frequency and code-phase characteristics of the detected message.
