Description: Frequency Synchronization in OFDM System
An accurate frequency synchronization method using the zadoff-chu (ZC) constant envelop preamble is analyzed, and a new preamble weighted by pseudo-noise sequence is used for orthogonal frequency division multiplexing (OFDM) systems. Using this method, frequency offset estimator range is greatly enlarged with no loss in accuracy. The range of the frequency estimation is ±30 of subcarrier spacing using ZC sequence as preamble. Simulations in the MATLAB for an AWGN channel show that the proposed method achieves superior performance to existing techniques in terms of frequency accuracy and range. Platform: |

OFDM is shown in figure 1.In order to achieve higher data
rate, the serial data stream bits are converted in to parallel data
output bits. Then the modulation schemes can be BPSK,
QPSK or QAM, which in turn assigns the complex data
points. The orthogonality between subcarriers is maintained
by IFFT and FFT pairs which also transforms frequency
domain components to time domain and vice versa. 64 point
IFFT is used in this methodology.) Platform: |
