Book synopsis

This book explores theoretical and practical aspects§of iterative decoding algorithms when they are§implemented on analog continuous-time platforms.§Analog continuous-time iterative decoding was§proposed a few years ago to improve the§power/speed ratio of decoder chips that decode§capacity achieving codes. It was commonly§believed that replacing discrete-time processing§modules with analog circuits would not change the§dynamics of the iterative decoder. On the contrary,§it is shown that not only does continuous-time§iterative decoding have different dynamics, but also§its error correcting performance can surpass that of§conventional iterative decoders. §Furthermore, novel processing modules for§implementing affordable§high-speed strongly inverted CMOS analog min-sum§iterative decoders are presented. This is favorable§because previously reported analog decoders were§either BiCMOS or weakly inverted CMOS designs. The§former could be fast but is rather expensive and§the latter would be low-power but it is not fast§enough for many applications.
