Listing of Communication in Scripts

Calculates exponential averaged RMS of a signal using the specified windowlength as the time constant. Useful for computing sound pressure level from microphone data. Uses digital filter. Much faster than cumsum..

This landmark-based audio fingerprinting system is able to match short, noisy snippets to a reference database in near-constant time. This is my implementation of the music audio matching algorithm developed by Avery Wang for the Shazam service. Shazam can identify apparently any commercial music track from a short snippet recorded via your cell phone in a noisy bar.

SMOOTHN provides a fast, unsupervised and robust discretized spline smoother for data of any dimension. SMOOTHN(Y) automatically smoothes the uniformly-sampled array Y. Y can be any N-D noisy array (time series, images, 3D data,...). SMOOTHN can deal with missing (NaN) values (see screenshot, top panels).

random_band is the main program and it outputs a test signal which has a constant level. The instanatenous frequency varies randomly within the specified Nth octave band range. The program outputs three plots: time record of the instantaneous frequency, time record of the instantaneous level, and a histogram of the spectral content.

For vectors, Y = RUNMEAN(X,M) computes a running mean (also known as moving average) on the elements of the vector X. It uses a window of 2*M+1 datapoints. M an positive integer defining (half) the size of the window. In pseudo code: Y(i) = sum(X(j)) / (2*M+1), for j = (i-M):(i+M), and i=1:length(X) For matrices, Y = RUNMEAN(X,M) or RUNMEAN(X,M,[]) operates on the first non-singleton dimension of X.

Useful for the RF designer, it manipulates the various complex representations of the circuits as multiports, namely transformation from one representation to another and reading/writing to file in industry-standard format it contains stuff written/revised between 1993 and 2003, therefore a quite a few things could be better done today, especially file parsing/writing; however, most of the transformations are singularity-protected and I think this toolbox can really help one to get insight when working at high frequencies.

Samplify for Matlab allows sampled data users (those capturing real-world samples from A/D converters, or sending samples to D/A converters) to compress these samples in one of three compression modes: a) SignalZIP (TM) lossless mode, b) Samplify fixed-rate mode (users specify the desired compression ratio) c) Samplify fixed-quality mode (users specify the desired dynamic range) Samplify for Matlab demonstrates the achievable rate-distortion tradeoffs (higher bit rates have lower distortion) of the Samplify compression algorithm.

ScaleTime - fast linear matrix interpolation I have recorded timeseries of e.g. size [100'000 x 10] and cut out chunks of about 100 frames according to some events and normalize them to exactly 100 frames. For this task, the direct approach with Matlab's INTERP1 works, but it is slow: interp1(1:size(Y, 1), Y, Ti, '*linear') Cutting Y to blocks of 1000 frames at first accelerates the computing, but encreases the complexity.

Unlike standard scatterplot() which doesn't allow you to plot on the current figure, this function works in a more conventional way (e.g. similar to plot()) and allows you to specify also a title string and the plot string (colour, marker). More important, it adds indexes of the plotted data samples next to each sample, making it easier to debug small data sets scatter-plotted.

A stack-based sequential depth-first decoder that returns Maximum-Likelihood solutions to M-QAM modulated MIMO system-type problems, i.e., a lattice decoder with optional justified rectangular boundary control. In such problems, the depth of the search tree is known and the number of children per node is also fixed.

FASTRMS Instantaneous root-mean-square (RMS) power via convolution. FASTRMS(X), when X is a vector, is the time-varying RMS power of X, computed using a 5-point rectangular window centered at each point in the signal. The output is the same size as X and contains, for each point in X, an estimate of the instantaneous power expressed in the signal.

Y = DCTN(X) returns the discrete cosine transform (DCT) of X. X = IDCTN(Y) returns the inverse discrete cosine transform (IDCT) of Y. Y = DSTN(X) returns the discrete sine transform (DST) of X. X = IDSTN(Y) returns the inverse discrete sine transform (IDST) of Y.

This toolbox includes a complete set of blocks implemented in the Simulink environment, which allows designers to perform time-domain behavioral simulations of switched-capacitor sigma-delta modulators. The proposed set of blocks takes into account most of the SC sigma-delta modulator non-idealities, such as sampling jitter, kT/C noise and operational amplifier parameters (white noise, finite dc-gain, finite bandwidth, slew-rate and saturation voltages).
