Dear WARP Team,
When we test the example code "wl_example_siso_ofdm_txrx.m" under the folder "WARPLab_Reference_Design_7.7.0\M_Code_Examples", we encounter this error "No LTS Correlation Peaks Found!". Can we have any comments on that? The tests of some other example codes like "wl_example_basic_txrx.m" or "wl_example_continuous_tx.m" look good without any error.
Thanks,
Ralph

What is the test setup? Is this over the air with antennas? Or through a wire with sufficient attenuation?
That print means that there were no correlation spikes in the "lts_corr" variable that were sufficiently high for the receive processing code to synchronize to. You'll have to plot "lts_corr" to see what happened. If it's borderline, you could try lowering "LTS_CORR_THRESH."

Hi chunter,
This is over the air with antennas.
Problem is solved... We didn't attach the proper antennas...
