Sliding window technique to detect the presence of LTE

This paper describes the synchronization signals used by the Long Term Evolution (LTE) with a main focus on the detection of the presence of LTE coverage. The LTE system uses its central 62 subcarriers for the purpose of synchronization and broadcast system information. We use sliding window technique over the fading channels with different number of channel taps to detect the presence of two synchronization signals which in turns indicates the presence of LTE.
