A comparative algorithm for OFDM based on multiple channel supported timing synchronization

In this paper, a wireless MAN OFDM systems algorithm based on robust timing synchronization has been proposed by us. A combination of FFT based timing and frame synchronization makes up the algorithm that is being proposed. The timing offset estimation presents an element of ambiguity in the use of the conventional correlation scheme for accurate symbol timing detection. However, the use of the preamble conjugate symmetric characteristic that has been proposed in this paper, presents a clear view at the correct timing. Moreover, it is also able to continuously control the position of the FFT window with the first order loop filter. In the end, the results of the simulation clearly showcase that the proposed algorithm gains superiority in comparison to the conventional one.
