LabVIEW Source Code: Modulator and Demodulator (BPSK, QPSK, 16QAM, 64QAM)

This page provides LabVIEW source code for modulators and demodulators (also known as mappers and demappers) implementing BPSK, QPSK, 16QAM, and 64QAM modulation techniques. You can find the download links for the LabVIEW VI source code below.

• BPSK: Binary Phase Shift Keying
• QPSK: Quadrature Phase Shift Keying
• QAM: Quadrature Amplitude Modulation

BPSK, QPSK, 16QAM, 64QAM Modulator (Mapper) LabVIEW VI Block Diagram

Figure 1 shows the block diagram of the modulator LabVIEW VI. This VI generates modulated data based on your selection of BPSK, QPSK, 16QAM, or 64QAM. It takes a binary vector of a user-defined size as input.
