4.5.7 Practical Code Generation—Hardware Implementation
The (7,4) code generator matrix in Equation (4.17) produces systematic codewords of the form [d1,d2,d3,d4,c1,c2,c3], where:
(4.22)
Figure 4.13 illustrates one possible hardware implementation of this encoding process using shift registers and modulo-2 adders. This architecture allows high-speed real-time generation of codewords in both digital logic and programmable devices.
