MATLAB: FM Stereo Receiver using RTL-SDR in Matlab

Communications Toolboxfmradioreceiverrtl-sdrsdr

Hi! I try to build own version of fm stereo receiver by modificate script from this article . Is it possible to demodulate signal and receive FM Radio by increasing sample rate of RTL-SDR (f.ex. from 0.24 MSPS to 2.4 MSPS) ?

Best Answer

You can change the sample rate. But, you need to make sure that all the other sample rates in the system are also modified to keep them in sync and compatible.

MATLAB: Error when running Pluto Radio QPSK Example

The 'plutoradioQPSKReceiverExample' throws the error:

 'QPSKDataDecoder' is used in QPSK Transmitter and Receiver

due to a missing file 'QPSKDataDecoder' in the Support Package path. Both the 'plutoradioQPSKReceiverExample' in Pluto Hardware Support and 'QPSKTransmitterAndReceiverExample' in Communications Toolbox use a common file 'QPSKDataDecoder' that is missing in the support package directory, and returns this error as a result.

To resolve this issue:

Click on the link "QPSK Transmitter and Receiver" in the error message

'QPSKDataDecoder' is used in QPSK Transmitter and Receiver

The current folder path will then be changed to the 'QPSKTransmitterAndReceiverExample' directory in the Communications Toolbox, in which 'QPSKDataDecoder' is available,

Next, execute:

>>addpath(pwd)

at the MATLAB Command Window to add this location to the MATLAB path. After doing so, 'plutoradioQPSKReceiverExample' and 'QPSKTransmitterandReceiverExample' will run successfully.

Type "edit RBDSExample" in MATLAB command window. It will open the file in the editor. In R2016b, the files are under the RTL-SDR support package directory tree.
