Overview

Demonstration on how to map a OFDM baseband signal to a QPSK constellation.

 

Description

This simple code shows how to map the OFDM baseband signal to a QPSK modulation scheme in order to convert the symbols to a parallel digital pattern. In order to accomplish this, we need a Word to Symbol map that can guide us. Also, we will be able to see the process on how to revert from a parallel digital pattern to symbols again.

 

Requirements

LabVIEW 2012 (or compatible)

 

Steps to Implement or Execute Code
1. Open the "Transform OFDM signal to Parallel Bits LV2012 - NI Verified.vi"
2. Select the Run button.
3. Change the Word to Symbol Map.
4. Observe the parallel word being updated after running the code again.
