IModulator

module interface

Interface 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:
