IModulator

Package: inet.physicallayer.wireless.common.contract.bitlevel

module interface IModulator

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.

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.
