4.5 Ofdm symbol decoder (receiver) (labview)

Input/outputs and help

Show above is the LabVIEW sub-VI for receiving generic OFDM symbols to be placed in any real-life communications template. It is designed to be the polar-opposite of the OFDM symbol generator demonstrated previously , but can easily be placed in cascade in higher level VIs to tailor to any OFDM system.

Note that this module will be built from previously discussed receiver modules, so if anything is completely alien, check the menu list to the left for information about each sub-VI contained here.

As promised, here is our receiver built from all our previous sub-VIs. Note that, as with the OFDM symbol generator, multiple functions are multiplexed in case they're unneeded to save computational complexity.

The VI is built such that it can easily take a transmitter property cluster used in the symbol generation to configure the receiver blocks. Everything seen here has been previously seen prior, and the only pitfall is the use of clusters. We're now ready to test the complete OFDM chain in software to verify the performance of our transceiver. For more information, check the instructional video below and the all software test shown in the left hand column of the collection.
