Hi everyone
I have implemented 802.11n Mimo-Ofdm on simulink and now i want to simulate it on FPGA via HDL coder. First i want to simulate Transmitter side having some math functions, constants , convolutional encoder, ifft's and 16 qam. but
I am constantly having problem in Checkpoint 1.3 of HDL workflow advisor giving following errors
Error : Frame based models are not supported for HDL code generation. Error : Matrices are not supported in this release.
i have also converted its format from double to sfix16_En13 to check it on different compatibility but same problem. kindly help me out of this problem
Simulation images are given below:

The error is about the fact that your input signal (coming from Bernoulli Random Binary Generator) is a frame-based signal. You will need to serialize your model (have the algorithm process one bit at a time, rather than a vector or matrix signal).
