Bit-Interleaved Coded Modulation: Fundamentals, Analysis and Design

2.6 Codes and Encoding

Throughout this book, we consider a rate binary encoder (see Fig. 2.18), where the information bits are mapped onto sequences of code bits , , where

Figure 2.18 The encoder ENC in Fig. 2.7 has rate and different “classes” of bits

Here, the index in the sequences represents a “class” of code bits sharing certain properties.⁵ While this description is not entirely ...
