Detailed Description

Declares classes used to implement bit mapping.

Bit mapping is used in modulator and Demodulator classes to assign a certain (of course unique) bit pattern to each signal space point of the used modulation schemes. E.g. one of the most common bit mapping schemes is the so-called Gray-mapping. See the book Digital Communications, Proakis for further explanation.

Enumeration Type Documentation

enum simthlib::map_type

Mapping for modulation symbols. Natural mapping is identical with mapping by set partitioning in the case of a one-dimensional modulation scheme. Enumeration values: GRAY  Gray mapping for up to 256 states. NATURAL  Natural mapping. PARTITIONED  Mapping by set partitioning.
