IDemodulator

module interface

Module interface for demodulators in wireless communication systems. Demodulators convert symbols back to bits in the receiver's signal processing chain. They take a reception symbol model as input and produce a reception bit model as output by applying the inverse of the modulation scheme (such as BPSK, QPSK, QAM16, etc.) to each symbol to recover the original bit sequence.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Implemented by

Name	Type	Description
ApskDemodulator	simple module	Part of a simple hypothetical layered receiver. It computes the bit domain representation from the symbol domain representation by applying the configured modulation.
Ieee80211OfdmDemodulator	simple module	<b>See also:</b> ~Ieee80211OfdmModulator

Used in compound modules

Name	Type	Description
ApskLayeredReceiver	compound module	This receiver model is part of a simple hypothetical layered radio. It receives 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 expected to be set on the reception.
Ieee80211LayeredOfdmReceiver	compound module	Implements an IEEE 802.11 OFDM receiver. The implementation details are based on the following standard: IEEE Std 802.11-2012 PART 11: WIRELESS LAN MAC AND PHY SPECIFICATIONS
