IModulator
module interfaceInterface for digital modulator modules that convert sequences of bits into sequences of symbols. Modulators implement various modulation schemes (such as BPSK, QPSK, QAM, etc.) that determine how digital information is encoded into changes in the carrier signal's amplitude, frequency, or phase. The modulator takes a bit model as input and produces a symbol model as output, forming an essential component in the physical layer signal processing chain for wireless communication systems.

Implemented by
| Name | Type | Description |
|---|---|---|
| ApskModulator | simple module |
Part of a simple hypothetical layered transmitter. It computes the symbol domain representation from the bit domain representation by applying the configured modulation. |
| Ieee80211OfdmModulator | simple module |
This is an IEEE 802.11 OFDM modulator module. The implementation is based on the 18.3.5.8 Subcarrier modulation mapping section in IEEE 802.11-2012 Std. |
Used in compound modules
| Name | Type | Description |
|---|---|---|
| ApskLayeredTransmitter | compound module |
This transmitter model is part of a simple hypothetical layered radio. It produces detailed transmissions that have a separate representation for all simulated domains. The levelOfDetail parameter controls which domains are actually simulated, but all parameters relevant to the error model are always set on the transmission. |
| Ieee80211LayeredOfdmTransmitter | compound module |
The level of detail parameter determines which submodules of the transmitter will be used: |
