Developer tools · MATLAB QPSK

Free Online MATLAB QPSK Generator

Generate QPSK baseband symbols and ready-to-run MATLAB code. Supports symbol count, samples-per-symbol, phase offset, Gray mapping, and one-click copy. Runs locally in your browser with zero uploads.

Generate QPSK

Random bits → QPSK mapping → (optional) rectangular upsampling by SPS, then output MATLAB script and preview data.

Symbols

Samples per symbol (SPS)

Phase offset (deg)

Mapping

Random seed (Optional)

Leave empty for true randomness; set an integer seed to reproduce results.

MATLAB Code

Run as-is to get bits, qpskSymbols (complex column vector), and optional basebandWaveform (repeated by SPS).

Preview

Shows the first 16 symbols (I/Q and complex form) so you can quickly verify mapping and phase offset.

k	b0 b1	I	Q	symbol

Notes

Use your own bitstream for real simulations. This tool is intended to bootstrap example scripts quickly.
For pulse shaping (RRC) or RF carrier modulation, extend the MATLAB script as needed.
