A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual member, a community, or a respected organization.

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.

Words-to-Bits (Receiver) (LabVIEW)

Module by: Bryan Paul. E-mail the author

Summary: This is the instructional module for construction and use of the words-to-bits sub-VI for our OFDM receiver chain. Though somewhat trivial in nature, keeping it as it's own sub-VI helps maintain modularity should we wish to pursue more advanced implementations in the future. Embedded is a tutorial video on the construction of the sub-VI, as well as an example video on how to use the function. The file is available for download below.

We come again to a seemingly undeserving sub-VI shown above. While it may not warrant a sub-VI at present, future implementations will benefit from it's separation from other sub-VIs. This way, upgrading and changing individual parts will have minimal impact on the adjacent subsystems.

The above figure is our simple implementation as discussed above. All we're doing is taking advantage of LabVIEW's reshape array function. We're reshaping our two dimensional array defined by the input integers to one continuous array comprising one dimension.

Note that optimal implementations at lower levels could be achieved implicitly by how the memory is mapped. Therefore this module is simply a convenient educational tool for transparency in observing the overall OFDM transceiver hierarchy. For any inquiries, check out the instructional video below in Figure 3, the example use video below in Figure 4, or email the author for more information.
