scripts default iconVersatile Modulator Publisher's description

Versatile Modulator - Template for signal manipulation GUI.

This GUI has been thought to be a templete for new projects that required signal manipulation.

GUI manipulate files. Those files must be created by the digital signal processor, and should contain the signals of the more relevant points of the systems.

Exists a function that works as interface between GUI and the processor. Changing that function properly allow to reuse the GUI on different projects.

On this example, a versatile modulator has been place as DSP.
Basically consists on a IQ modulator used for M-ASK, M-QAM, BPSK, QPSK modulated signal generation.


A.- Not heavily test, and not finshed yet.

B.- Block processing style: so, generate an process a set of samples, then the next set, etc. This allow to process a large amount of samples on a reasonable time, cause the memory is not overloaded.

C.- Bits representation over signals does not work fine yet.

D.- Easy implementation: easy to understand and with few well commented functions and scripts to config.
All the system is distributed on a folder hierarchy, each folder with the functions related to one specific goal.

E.- Constelation calculation wrong: cause it is not well considered the group delay of the raise cosine filter.

F.- Take special care on:
F.1.- Time vector definition: in order to continue properly the time axe between blocks
F.2.- Memory manipulation: to extract the initial conditions and save the final conditions of each block properly.

G.- DSP environment parameters: memory can also be used to keep all the required environment of the DSP (filters coeficients, flags, initial conditions of the system for the incoming block, etc.).
