“…Many valuable methods have been investigated [4][5][6][7][8][9][10][11][12][13][14]. Methods based on polyphase filterbank [4][5][6] and interpolation of signal samples [7][8][9][10][11] are used mostly, and mainly discussed in this paper. The feedforward-loop symbol timing recovery technique [12] performs timing estimation followed by an interpolation of the signal samples.…”

This paper presents a symbol timing synchronization method by interpolating the discrete impulse response of matched-filter, in which the group delay of matched-filter is adjusted by different interpolation step to achieve symbol timing synchronization. The proposed method is of much less complexity than the conventional polyphase filterbank method that could be viewed as a special case of interpolated matched-filters. The interpolated matched-filters are used in a loop, and the loop is simulated at 2 samples/symbol, the simulation results show that the proposed method can provide precise symbol timing synchronization with less complexity.
