In this paper, we study the performances of preambles with a weighted structure for estimate the Timing Offset and Frequency Offset in Orthogonal Frequency Division Multiplexing (OFDM) systems. We have reviewed the configuration in short and long preambles of weighted preambles, based on Constant Amplitude Zero Auto Correlation (CAZAC) sequences weighted by a Pseudo Noise (PN) sequences. In this paper...
In order that an User Equipment (UE) can access a cell in a Long Term Evolution (LTE) systems, it must be able to perform an initial synchronization and search for a base station (eNodeB) to establish the downlink (DL) access. This process is called the initial cell search. Two synchronization signals are available to accomplish this process: the primary synchronization signal (PSS) and the secondary...
