myreceived_data is not a Mathworks function, but the problem is occurring inside it. We would need the code.

Thank you very much dear Walter Roberson for your response. The requirede function is as below:
%1-Received data
function recvd_data = myreceived_data(Nc,N_bar,N,M,K,tot_len,array_TX,DOD,array_RX,DOA)
recvd_data1 = zeros(N,tot_len*Nc);
shift_data = zeros(N_bar,tot_len*Nc,M,K);
for m = 1:M
for k = 1:K
shift_data(:,:,m,k) = circshift(data_tx_ss(:,:,m),[0,delays(m,k)]); % Shift circularly columns of matrix towards right
end
end
for m = 1:M
for k = 1:K
for t = 1:tot_len
S_TX = spv(array_TX, [DOD(k+(m-1)*K) 0]);
S_RX = spv(array_RX, [DOA(k+(m-1)*K) 0]);
recvd_data(:,Nc*(t-1)+1:Nc*t) = recvd_data1(:,Nc*(t-1)+1:Nc*t) + (beta(k+(m-1)*K,t)*S_RX).*(S_TX'*shift_data(:,Nc*(t-1)+1:Nc*t,m,k));% it is x(t) in eq.(6)
end
end
end
end % function end

When calling the function, you are missing the variable N_bar.

Because Array_TX is not defined by that code.
