INITIAL CELL SEARCH ALGORITHM

摘要

A system and method for establishing initial synchronization for the link
between a UE and a base station in a communication network uses window
exclusion
logic in order to avoid a deadlock condition upon a detection of the wrong
public land
mobile network (PLMN). The communication signal is processed in a three step
decision process. The first decision step determines a chip offset of the
strongest path
detected over a frame of samples. In response to the first decision, the
second step
generates a scrambling code group number and slot offset for retrieving the
secondary
synchronization code. The third decision step retrieves a primary scrambling
code in
response to the code group number for synchronizing the UE to the base
station.
