This repository contains some simulation macros related to signal processing. The macros have been built using Matlab and Python.

Pitch frequency measurement, periodogram of each vowel, voice spectrum analysis and cepstrum FFT. This macro can be found at "voice-processing/" directory.

Tracking of a geostationary orbit using extended Kalman filtering. A filter is implemented that performs the prediction from a dynamic model and provided measurements.

The equalization of a QAM-16 signal transmitted through a multipath channel can be found at "equalizer/" directory. The simulation has been carried out for a static channel (TSE-LS) and for a changing channel (TSE decision-directed). This simulation can be found at "/equalizer" directory

At "image-processing/" directory you can find two different macros:

• An implementation of a JPEG compression
• Image enhancement and 2D filters

This macro implements the decoding of a DVB-T channel, visualizing TPS carriers. PD: The signal is not provided but it can be recorded by a RTL-SDR The code can be found at "DVB-T/" directory.

An acoustic delay and sum beamformer has been implemented in order to enhance an audio signal. Directivity patterns are also shown.
