How to combine 340 sub matrices of 117 by 1 into one matrix of 9945 by 1. I'm working on ofdm(subcarriers=128, cp length=32) and got 117 data carriers. That's why ofdm requires input matrix of 117 by 1

kindly tell me how to combine these subsets in one matrix. for example I'm working on following lines.

numSC = 128; % Number of OFDM subcarriers

cpLen = 32; % OFDM cyclic prefix length

ofdmMod = comm.OFDMModulator('FFTLength',numSC,'CyclicPrefixLength',cpLen);

ofdmDemod = comm.OFDMDemodulator('FFTLength',numSC,'CyclicPrefixLength',cpLen);

channel = comm.AWGNChannel('NoiseMethod','Variance', ...

'VarianceSource','Input port');

ofdmDims = info(ofdmMod)

numDC = ofdmDims.DataInputSize(1)

st=rand(9945,4)

for n=1:85

Baserow = (n-1) * 117;

for n1 = 1:4

Subset = st(Baserow+(1:117),n1, :)

txSig = ofdmMod(Subset);

>> y = awgn(txSig, SNR(k));

>> sigRx = ofdmDemod(y); % gives 340 sub matrices of "Sigtx" of 117 by 1. How to combine them in a single matrix?

end

end

C = cell(4,85);

...

for ii = 1:85

...

for jj = 1:4

sigRx = ...

C{jj,ii} = sigRx;

end

end

V = vertcat(C{:})

but getting folllowing error

C{jj,ii} = sigRx;

↑

Error: The expression to the left of the equals sign is not a valid target for an assignment.

how to fix this error?
