In this paper, we investigate the timing and carrier frequency offset (CFO) synchronization problem in decode and forward cooperative systems operating over frequency selective channels. A training sequence which consists of one orthogonal frequency-division multiplexing (OFDM) block having a tile structure in the frequency domain is proposed to perform synchronization. Timing offsets are estimated using correlation-type algorithms. By inserting some null subcarriers in the proposed tile structure, we propose a computationally efficient subspace decomposition- based algorithm for CFO estimation. The issue of optimal tile length is studied both theoretically and through simulations. By judiciously designing the tile size of the pilot, the proposed algorithms are shown to have better performance, in terms of synchronization errors and bit error rate, than the time-division multiplexing-based training method and the computationally demanding space-alternating generalized expectation-maximization

This sourcecode extracts de melcepstrum coefficient of an audio file. You should give to de function, the audio file save as a vector, and the function returns a vector with 23 melcepstrum coefficients.

Simulink toolbox provides the user with two ways to create S-functions in C: with the automatic builder S-Function Builder and manually, using a template (similar to the creation of S-functions written in MATLAB).
