Description: MFCC (Mel Frequent Cepstral Coefficient) in M-File.
epresentation of the short-term power spectrum of a sound, based on a linear cosine transform of a log power spectrum on a nonlinear mel scale of frequency.
MFCCs derived as follows:
1. Take the Fourier transform of (a windowed excerpt of) a signal.
2. Map the powers of the spectrum obtained above onto the mel scale, using triangular overlapping windows.
3. Take the logs of the powers at each of the mel frequencies.
4. Take the discrete cosine transform of the list of mel log powers, as if it were a signal.
5. The MFCCs are the amplitudes of the resulting spectrum.

Description: This paper describes two digital implementations of a new mathematical transform, namely,
the second generation curvelet transform [12, 10] in two and three dimensions. The first digital
transformation is based on unequally-spaced fast Fourier transforms (USFFT) while the second is
based on the wrapping of specially selected Fourier samples. The two implementations essentially
differ by the choice of spatial grid used to translate curvelets at each scale and angle. Both
digitaltransformations return a table of digital curvelet coefficients indexed by a scale
parameter, anorientation parameter, and a spatial location parameter. And both implementations are
fast in
the sense that they run in O(n2 log n) flops for n by n Cartesian arrays in addition, they are
also invertible, with rapid inversion algorithms of about the same complexity.-This paper describes two digital implementations of a new mathematical transform, namely,

Description: Leung-Malik (LM)滤波器组由48个滤波器组成-The LM set is a multi scale, multi orientation filter bank with 48 filters. It consists of first and second derivatives of Gaussians at 6 orientations and 3 scales making a total of 36 8 Laplacian of Gaussian (LOG) filters and 4 Gaussians. We consider two versions of the LM filter bank. In LM Small (LMS), the filters occur at basic scales . The first and second derivative filters occur at the first three scales with an elongation factor of 3 (i.e. and ). The Gaussians occur at the four basic scales while the 8 LOG filters occur at and . For LM Large (LML), the filt ers occur at the basic scales

Description: Large-scale variations caused by shadowing of obstacles are shown to follow a log-normal distribution [17][18][19], which means that when measured in dB they follow a Gaussian distribution. Consequently shadowing effects are usually incorporated into path loss estimates by the addition of a zero-mean Gaussian random variable, with standard deviation σ: N(0,σ), were σ is often estimated by empirical measurements. Commonly accepted values for σ are between 6 dB and 12 dB. Measured values of σ itself seem to display Gaussian distribution as well, in their variations from one area to another, and depend on the radio frequency, the type of environment (rural, suburban, or urban), base station and subscriber station height.
