Review on Comparison of Different OFDM Symbol Timing Synchronization Algorithms

Orthogonal Frequency Division Multiplexing (OFDM) is the key technology for 4G and 3GPP LTE systems due to its highly efficient bandwidth and multi carrier modulation. The benefit of using OFDM is that it avoids ISI (Inter Symbol Interference) and ICI (Inter carrier Interference) by using timing synchronization technique. For this the symbols must be in properly synchronized form. It also have Higher transmission rate. So SC (Schmidl and Cox) algorithm is designed, It provides timing synchronization and lowers BER (Bit Error Rate). Based on the research of Schmidl & Cox, Minn and Bhargava and Park et al. synchronization algorithm, this paper proposed a comparison on these three timing synchronization algorithms.
