In chapter4.m vec2mat is used, but that is now depreciated. Matlab recommends using reshape instead. The easiest solution is to replace vec2mat with reshape(arr, [], numcols)

The function SetPlotSize and SetPlotFont used in the code is undefined, they are used in the following list of files:

chapter.m 
chapter2.m
chapter3.m
chapter4.m
chapter5.m
chapter6.m
psk.m
robin.m
sfdr_test.m
simulated_DAC.m
time-alias.m
updownsample.m

I am using MatLab R2018a, I'll update this issue with any undefined or missing functions found in the examples as I come across them.

I'm unsure if this is intentional or not. The supporting text does not mention what is supposed to happen to zeroes.

Assuming the purpose of the source encoding is to just replace strings of 1s with a number representing the length of said strings, then the zero preceding the string is erroneously removed from the encoded message (in reality that zero's position is used for the string length value). As a result, a binary message starting "01101110..." and a binary message starting "1101110..." both encode to decimal message "2,3,...".

Given that source encoding is meant to be a unique mapping from one domain to another, the example code gives rise to a non-unique mapping, where by "2,3" is not uniquely decode-able back to the original binary message.

I would have assumed that the zeroes have to be left well alone(?) and therefore the above messages should encode to "0, 2, 0, 3,..." and "2, 0, 3, 0,..." respectively.
If that assumption is correct, then adding:

if (enc_msg1(end) == 0)
     enc_msg1 = [enc_msg1 0];
endif

between lines 81 and 82, and 90 and 91 should resolve the issue; preserving all zeroes in the encoded message EDIT: remembering to ammend the variables numbers accordingly....

Example code is Code 4.2, in file chapter4.m

I ran the following code modified from template3.m.

framesToCollect = 1000;
frameSize = 2^15;
rx = sdrrx('Pluto');
rx.SamplesPerFrame = 2^15;
rx.CenterFrequency = 430e6;

%% Template 3
% Perform stream processing
sa3 = dsp.SpectrumAnalyzer;
sa3.SampleRate = 1e6;
framesToCollect = 1000;
% Process each frame immediately
for frame = 1:framesToCollect
    [d,valid,of] = rx();
    % Process data without overflow and is valid
    if ~valid
        warning('Data invalid')
    else
        if of
            warning('Overflow occurred')
        end
        sa3(d); % Algorithm processing
    end
end

But I got an overflow warning.

>> template_3
## Establishing connection to hardware. This process can take several seconds.
Warning: Overflow occurred 
> In template_3 (line 20) 

I cant think of why an overflow might occur. My frameSize and sampling rate tally. Might someone be able to tell why?

Hi,
I was looking for some implementation of Schmidl-cox and I bumped onto this book and pluto-SDR and its really amazing.
I was trying to run the code and guess have a dependency on getOFDMPreambleAndPilot function. What toolbox do I need in order to successfully run all the codes on this git? Or Do I need to implement this on my own ?
