IInterleaver

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

module interface IInterleaver

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.

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)
