Lenses

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.

What are tags? tag icon

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

hamming_GeneratorMatrix.vi

Module by: Ed Doering. E-mail the authorEdited By: Brett Hern, Erik Luther, Sam Shearman

Summary: Build a LabVIEW subVI to create the generator matrix (G matrix) for the (n,k) Hamming linear block code.

Table 1
LabVIEWtop.png This module refers to LabVIEW, a software development environment that features a graphical programming language. Please see the LabVIEW QuickStart Guide module for tutorials and documentation that will help you:
• Apply LabVIEW to Audio Signal Processing
• Get started with LabVIEW
• Obtain a fully-functional evaluation edition of LabVIEW

Note:

Visit LabVIEW Setup to learn how to adjust your own LabVIEW environment to match the settings used by the LabVIEW screencast video(s) in this module. Click the "Fullscreen" button at the lower right corner of the video player if the video does not fit properly within your browser window.

LabVIEW SubVI: hamming_HammingCodeParamters.vi

  • Description: Create the generator matrix (G matrix) for the (n,k) Hamming linear block code, as well as the parity matrix (P matrix), given the number of checkbits "q" and the message length "k".
  • Category: Hamming (n,k) block code ("hamming" prefix)

Inputs (Controls)

  1. q, checkbits (3) -- I32
  2. k, message length (4) -- I32

Parentheses ( ) indicate default value; square brackets [ ] designate units.

Outputs (Indicators)

  1. G matrix, k by n -- Real Matrix
  2. P matrix, k by q -- Real Matrix

Required Behavior

  1. "P" is a k by q matrix of q-bit words containing two or more 1s arranged in any order (or, equivalently, the minimum Hamming weight of each row of the "P" matrix is 2).
  2. "G" is defined as [I | P], where I is the k by k identity matrix.
