GNU Radio is open-source software where in we use signal processing blocks to implement communication system applications. Flexibility provided by GNU Radio is good and it can be made best by using RF hardware along with GNU Radio, this helps to implement many wireless applications and software radios.
The GNU Radio Companion (GRC) is always a superior and satisfactory choice to create flow graphs, provided that all the blocks you need are available in GRC.
As I carry out basic experiment on GNU Radio platform I am excited to take one step forward. So I chose to work on quantization. Processes of quantization is done at transmitter side.
For quantization, the three main issues are:
- How many quantization levels should we choose
- How should the value of the levels be chosen
- How should we map the values of the original signal to one of the quantization levels
Quantization is done after sampling and quantization is a lossy process because approximation of value is done at final stages.
Sampling and Quantization are applied to analog signal based on sampling rate quantization may vary. Ones sampling and quantization are successfully applied then signal is called as digital signal
