IInterleaver

module interface

Module interface for bit-level interleavers used in wireless communication systems. Interleavers rearrange the order of bits in a data stream to spread the effects of burst errors, improving the performance of forward error correcting codes. Implementations provide methods for interleaving and deinterleaving bit sequences according to specific patterns.

Inheritance diagram

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

Implemented by

Name	Type	Description
Ieee80211OfdmInterleaver	compound module	The ~Ieee80211OfdmInterleaver is defined by a two-step permutation. The first permutation ensures that adjacent coded bits are mapped onto nonadjacent subcarriers. The second ensures that adjacent coded bits are mapped alternately onto less and more significant bits of the constellation and, thereby, long runs of low reliability (LSB) bits are avoided. (IEEE 802.11, 18.3.5.7 Data interleaving)

Used in compound modules

Name	Type	Description
ApskDecoder	compound module	Part of a simple hypothetical layered receiver. It computes the packet domain representation from the bit domain representation by applying the configured descrambling, forward error correction decoding, and deinterleaving.
ApskEncoder	compound module	Part of a simple hypothetical layered transmitter. It computes the bit domain representation from the packet domain representation by applying the configured scrambling, forward error correction encoding, and interleaving.
Ieee80211OfdmDecoder	compound module	This is the decoder module for the layered IEEE 802.11 OFDM PHY infrastructure (IEEE 802.11-2012, Clause 18).
Ieee80211OfdmEncoder	compound module	This is the encoder module for the layered IEEE 802.11 OFDM PHY infrastructure (IEEE 802.11-2012, Clause 18).
