41. Coding, Modulation and Multiuser Decoding for DS-CDMA Systems
Sammanfattning : The general trend both in wireless and fixed network communication systems is flexibility in services, data rates, desired delay and performance. Future systems should not be designed for specific services but be more general and allow for a multitude of services, both now existing and those not yet invented. LÄS MER
42. On the Design of Turbo Codes
Sammanfattning : 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. LÄS MER
43. On the Construction and Analysis of Iteratively Decodable Codes
Sammanfattning : Iterative decoding methods allow efficient decoding of long codes that are composed of smaller component codes. As a result reliable communication can be achieved with low decoding complexity even for rates close to Shannon capacity. This makes iteratively decodable codes a very attractive object of study in modern coding theory. LÄS MER
44. On Probabilistic Shaping and Learned Decoders with Application to Fiber-Optic Communications
Sammanfattning : We live in an ubiquitously connected world whose backbone are optical fibers. Achieving high spectral efficiencies and hence high transmission rates requires a careful combination of forward error correction (FEC) and higher-order modulation. This is referred to as coded modulation. LÄS MER
45. Iteratively Decodable Convolutional Codes: Analysis and Implementation Aspects
Sammanfattning : This thesis addresses the theory and implementation aspects of iteratively decodable codes. Iteratively decodable codes include, in particular, Gallager's regular low-density parity-check (LDPC) codes, Tanner's generalized LDPC (GLDPC) codes, turbo codes due to Berrou et. al. and expander codes.
