Here is the code for BPSK modulation and demodulation:
bpskModulator = comm.BPSKModulator;
bpskDemodulator = comm.BPSKDemodulator;
errorRate = comm.ErrorRate;
awgnChannel = comm.AWGNChannel('BitsPerSymbol',1);
ebnoVec = 5:10; % Eb/No range
berBPSK = zeros(size(ebnoVec));
for n = 1:length(ebnoVec)
% Reset the error counter for each Eb/No value
reset(errorRate)
% Reset the array used to collect the error statistics
errVec = [0 0 0];
% Set the channel Eb/No
awgnChannel.EbNo = ebnoVec(n);
while errVec(2) < 200 && errVec(3) < 1e7
% Generate a 1000-symbol frame
data = double(codeword);
% Modulate the binary data
modData = bpskModulator(data);
% Pass the modulated data through the AWGN channel
rxSig = awgnChannel(modData);
% Demodulate the received signal
rxData = bpskDemodulator(rxSig);
% Collect the error statistics
errVec = errorRate(data,rxData);
end
% Save the BER data
my question is, How do I get the value of rxData if the eb/no value is 6?

If understood correctly, here is how to get it:
...
for n = 1:length(ebnoVec)
% Reset the error counter for each Eb/No value
reset(errorRate)
% Reset the array used to collect the error statistics
errVec = [0 0 0];
% Set the channel Eb/No
awgnChannel.EbNo = ebnoVec(n);
while errVec(2) < 200 && errVec(3) < 1e7
% Generate a 1000-symbol frame
data = double(codeword);
% Modulate the binary data
modData = bpskModulator(data);
% Pass the modulated data through the AWGN channel
rxSig = awgnChannel(modData);
% Demodulate the received signal
rxData = bpskDemodulator(rxSig);
% Collect the error statistics
errVec = errorRate(data,rxData);
end
% Here is how to get the value (s) of rxData:
if n==2
D_ebno6=rxData; % Stored under this variable
% disp(rxData)
end
% Save the BER data
end
