This model is an 8-ary modulator/demodulator based on Pulse Amplitude Modulation (PAM). You can change the Eb/N0 parameter in the "AWGN Channel" block to see the effect of the channel noise on the demodulated signal while the simulation is running. The input is a sinusoid with a frequency of 1 Hz.

The main program is Main_sound_and_vibs.m. Up to 100 metrics are for each of sound, hand arm vibrations, whole body vibrations, and motion sickness. Main_sound_and_vibs calls the primary depedent function "Continuous_Sound_and_Vibrations_Analysis" which contains the switch statement controlling the data flow.

Sub band processing is based on splitting the frequency range into M segments (subbands),which together encompass the entire range. Each subband is processed independently, as called for by the specific application. The subbands are recombined after processing, to form an output signal whose bandwidth occupies the entire frequency range.

These are two M-files 'fourier1' and 'fourier2' The first is designed to demonstrate how triangular, rectangular, saw tooth, half wave and full wave rectified signals can be built from superposition of a predefined no of Fourier harmonic terms. It demonstrates how increasing the number of terms included in the summation will improve the signal shape.

If applied to a matrix, the function FILTFILT (Signal Processing Toolbox) calls itself recursively for each column. Internally FILTER is called twice, but this can be performed with a matrix directly to avoid the unnecessary overhead. For a [100 x 100] matrix FILTFILT is about 10 times faster with the patch! The function PatchFILTFILT creates a copy of the original function and modifies the source such, that matrix arguments are processed directly.

This function is written to understand and/or explain an fft algorithm and usage of radix2 procedure. This function take the signal which you want to find FFT, for m bit you can also call the function without entering a signal or number of points, because there is default values for y and m which are; y = sin(2*pi*50*t)+sin(2*pi*120*t); m=3; you can see the steps of order reversing used as built-in function but non others.

The function implement the 2D dyadic(Paley) ordered fast in-place Walsh-Hadamard transform, which can be used in signal processing, pattern recognition and Genetic alogorithms. This algorithm uses a Cooley-Tukey type signal flow graph and is implemented in N log2 N additions and subtractions.

This function returns N point DFT samples of 2dw band of Fourier transform of a sequence. Typically, fft() returns N samples of Fourier transform ranging from 0 to 2pi. This function takes the N-point DFT samples and returns N-point samples corresponding to frequency band wc-dw to wc+dw.
