摘要:
A method for controlling integration for a CDMA signal and a receiver implementing the same. In accordance with the present invention, non-coherent and even coherent integration periods for a received signal are dynamically and adaptively controlled depending upon the condition of the received signal. The integration period can be very short when signal strength is strong and no blocking exists; while it can be extended to be longer when the signal strength is weak or there is a blocking. Therefore, it is possible to keep locking even under bad circumstances. In addition, the fix time can be shortened when the signal strength is very strong.
