A new hybrid acquisition scheme for CDMA systems employing short concatenated codes
… Scheme for CDMA systems employing Short Concatenated Codes. A new coding scheme using short concatenated codes is presented along with a detailed description of a new hybrid acquisition scheme. Simulation studies of the scheme are performed in a multiple access and additive white gaussian …

Performance of error correcting codes with random and burst errors
… capability of some classes of error correcting codes is analysed and their performance with both types of errors is tested. Reed Solomon and concatenated codes are examined in more detail because they are known to be among the best classes of codes. In order to evaluate the performance of these …

Optimum implementation of BCH codes
The Bose-Chaudhuri-Hocquenghem (BCH) codes are best constructive codes for channels in which error affect successive symbols independently. The binary BCH codes, a subclass of BCH codes, are known to have good random error correcting capability and Reed-Solomon (RS) codes, an important subclass of …

A channel emulation viewpoint of coding theorems
… We prove the error probability bound of concatenated codes from the channel emulation viewpoint, and derive the evolution of deficiencies of polar codes. We show that the analysis from the emulation and deficiency viewpoint matches the existing results in coding theory, and expect that …

Trellis-based iterative decoding of block codes for satellite ATM
… channels such as satellite links, error control codes are needed to provide high performance at very low Signal-to-Noise Ratios (SNRs). Turbo Codes or concatenated codes with iterative decoding, can achieve a performance very close to the Shannon limit. They are the most powerful codes known so …

On The Design Of Physical Layer Rateless Codes
Codes that are capable of generating any number of encoded symbols from a given number of source symbols are called rateless codes. Luby transform (LT) codes are the first practical realization of rateless codes while Raptor codes are constructed by serially concatenating LT codes with high-rate …

Fault-tolerant quantum computer architectures using hierarchies of quantum error-correcting codes
… fault-tolerance using quantum error-correcting codes is one of the most promising and versatile of the known routes for fault-tolerant quantum computation. This dissertation presents three main, new results about code-based fault-tolerant quantum computer architectures. The first result is a …

On the Design of Turbo Codes
This thesis is about Turbo codes - codes constructed via parallel concatenation of two recursive convolutional encoders linked by an interleaver. The focus of the work is on the understanding and design of Turbo codes. This includes thorough investigation of central components that influence Turbo …
