Example 2: OFDM Loop Back Test

⚫

This example familiarizes user with the OFDM transmission on the YTPC100 platform.

⚫

Ensure that cables or antennas connected to the YTPC100 TX1-RX1.

⚫

If user need to know the signal specifications, please refer to YTPC100x SISO_OFDM.pdf

⚫

path: “ .\release\Demo_Code_for_YTPC100\OFDM_EVM_Test_SISO\Test_EVM_TXLB.m “



Program:



Plot Result: QPSK/16QAM/64QAM/256QAM/1024QAM

6.4

DE Mode : RX_DE()

⚫

RX_DE(number_of_rows)

⚫

Use the number of rows in data to determine how many antennas to use to receive signals.
