I don't recognize the "wl_example_siso_ofdm_txrx_overshadowing.m" filename. Assuming it is a modification of our "wl_example_siso_ofdm_txrx.m" and remains similar, you can adjust the PHY rate by adjusting the MOD_ORDER variable. Values that are supported in the example are (2: BPSK, 4: QPSK, 16: 16-QAM, 64: 64-QAM). The other way to affect the transmit rate is to add channel coding to the example.

The WARPLab ref design uses a fixed 40MSps sample rate. The OFDM examples use 2x interpolation/decimation for a 20MHz-bandwidth signal. You can further adjust the bandwidth with more rate-change filtering in the m code.
