False channel detection for wireless communication
First Claim
1. An apparatus comprising:
- at least one processor configured to detect for a peak corresponding to a signal from a base station, to perform frequency acquisition and time tracking of the peak, and to determine whether the signal is from a desired frequency channel or a false frequency channel; and
a memory coupled to the at least one processor.

Abstract
Techniques for detecting acquisition of a false channel in a wireless communication system are described. For false channel detection, a peak corresponding to a signal from a base station is initially detected. Frequency acquisition and time tracking of the peak are then performed. The frequency acquisition attempts to determine and correct downconversion frequency error. The time tracking attempts to follow the peak as it moves due to sample timing error and/or changes in channel conditions. Whether the signal is from a desired frequency channel or a false frequency channel is determined based on the time tracking. If a false channel is acquired, then the sampling timing will be either too slow or too fast, and the peak will move at a fast rate. A false channel may be detected based on the movement of the peak.
