Third Generation Partnership Project (3GPP) Long Term Evolution(LTE) provides high spectral effciency, high peak data rates and frequency exibility with low latency and low cost. Usage of modulation techniques like OFDMA and SCFDMA enables LTE to achieve such requirements.However it is well known that OFDM systems like LTE are very sensitive when it comes to carrier frequency off- sets and symbol synchronization errors.Inorder to transfer data correctly, the User Equipment(UE) must perform both uplink and downlink synchronization with the Base station(eNodeB). In this thesis, Primary Synchronization Signal(PSS) and Secondary Synchronization signal(SSS) are used to detect the cell-ID of the best serving base station and also to achieve downlink synchronization whereas Physical Random Access Channel(PRACH) preamble is used to obtain uplink synchronization. PSS and SSS helps to achieve downlink synchronization by estimating the frame timing and carrier frequency offsets.In this thesis a non-coherent detection approach is followed for detection of both PSS and SSS signals.
