The pilot tones were not considered by the OFDM transmitter therefore only data points are
visible on the constellation. It can be seen that while the EVM for the 23km fibre

3dBm RF drive power. In real systems, however, high RF drive powers 
would be required in order to increase the conversion efficiency resulting in greater non
effects and consequently more symbols in error.

wireless standards and the need to integrate those with optical networks, co
capabilities between VPI and the well established software platforms for wireless simulations, 
such as MATLAB, are required. To that extent, this section attempts to present
