Abstract: 

Although considerable amount of research has been done on cognitive radio systems, very few works have been performed specific to LTE systems.  Researchers are still applying existing dynamic spectrum access (DSA) algorithms to evaluate the performance of LTE systems.  Efficient dynamic spectrum sensing techniques for LTE systems will be very helpful to wireless communication service providers, US Army, and other companies trying to efficiently utilize their frequency spectrum.  The primary goal of this project is to detect the presence of LTE coverage and derive the relevant analysis for calculating threshold and the probability of detection. In the LTE system, each cell is identified by the cell identification (cell-ID) and that information is carried by both the primary synchronization signal (PSS) and the secondary synchronization signal (SSS). 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 PSS signal which in turn indicates the presence of LTE
