Abstract
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 we have designed short and long preambles with a CAZAC sequence weighted by a Golay Rudin Shapiro sequence and their respective timing metrics. By simulation in MATLAB, we get the Mean Square Error (MSE) of the estimation, the Bit Error Rate (BER) of transmitted data over Rayleigh fading channel with Additive White Gaussian Noise (AWGN), coarse timing and frequency offset.
