IScrambler

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

module interface IScrambler

Module interface for scramblers that convert input bit sequences into seemingly random output sequences of the same length. Scramblers are used in wireless communication systems to randomize data, avoid long sequences of identical bits, improve clock recovery, and reduce transmission errors. Implementations typically use generator polynomials and seed values to define the scrambling algorithm. This interface supports both scrambling and descrambling operations needed in encoders and decoders of various wireless protocols.

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.
