On the Design of Analog VLSI Iterative Decoders

The rapidly growing electronic networking of our society has created the need for a high-speed and low-power data communications infrastructure. Both voice and data communications have been made available for the mobile user. Additionally, more complex coding schemes and decoding algorithms have been introduced to protect the user data from corruption during the transmission over a communications channel. The aim of all these new coding and decoding approaches is to meet the theoretical channel capacity limit to make a better use of the signal power and channel bandwidth. The iterative probabilitypropagation -type algorithms that are used to decode state-ofthe -art codes such as Turbo codes and low-density parity-check codes create the need for a tremendous computational power. Often, the computational complexity can not be implemented with a traditional digital design approach and a given power budget. This thesis discusses the efficient implemention of high-performance decoding algo..
