matlab-generate-wlan-waveform

What it does

Generates standard-compliant IEEE 802.11 waveforms for device testing, link-level simulation, or signal analysis. This skill covers the transmit chain: configure the PHY format, size the payload, generate the time-domain IQ waveform, and plot.

How it works

Follows a six-step workflow: select format to create a config object, configure PHY (bandwidth, MCS, spatial streams, antennas), size the payload (PSDU length or by target duration), create payload bits (random bits or MAC frame via wlanMACFrame), generate waveform with wlanWaveformGenerator(bits, cfg), and plot/verify using a time-domain magnitude plot and showAllocation when applicable.

Format selection maps Standards to config constructors (e.g., 802.11n -> wlanHTConfig, 802.11ac -> wlanVHTConfig, 802.11be -> wlanEHTMUConfig or wlanEHTTBConfig, 802.11bn UHR uses helpers). UHR requires R2026a or later for some features. The toolset includes functions like wlanSampleRate(cfg), wlanPSDULength, wlanAPEPLength, transmitTime, and per-user payload handling for MU/OFDMA scenarios. For HE/EHT/UHR, allocation indices and per-user parameters are specified; EHT DUP mode can be configured via EHTDUPMode=true. The skill includes concrete MATLAB code patterns for single-user, MU-MIMO, OFDMA, TB uplink, and multi-packet waveforms.

Patterns

• Single-User Waveform with Target Duration uses wlanVHTConfig with APEPLength or PSDULength depending on format.
• HE-MU OFDMA and EHT-MU OFDMA use per-user User{u}.MCS, APEPLength, NumSpaceTimeStreams, and RU allocation indices or MRU patterns.
• Non-OFDMA MU-MIMO for EHT/HE uses per-user configuration on a single RU with psduLength(cfg) to read per-user PSDU length.
• Trigger-Based Uplink uses wlanHETBConfig, wlanEHTTBConfig, or uhrTBConfig with RU indices from ruInfo(cfgMU).

What it can touch

• Functions: wlanWaveformGenerator, wlanSampleRate, wlanMACFrame, showAllocation, ruInfo.
• Config constructors: wlanNonHTConfig, wlanHTConfig, wlanVHTConfig, wlanHESUConfig, wlanHEMUConfig, wlanHETBConfig, wlanEHTMUConfig, wlanEHTTBConfig, uhrMUConfig, uhrTBConfig, wlanEHTMUConfig; per-user and RU parameters under cfg.User{u} and cfg.RU{r}.

Caveats

• NOT for channel modeling, receiver processing, EVM/spectral mask. Not covered: non-WLAN standards.
• UHR (802.11bn) support requires R2026a or later; inform users if their release is older.
• getPSDULength/psduLength are not interchangeable across formats.
• License provided via MathWorks license URL; no explicit software license text in the skill.
