The combination of low-density parity-check (LDPC) codes and higher-order modulation represents one of the most powerful digital transmission schemes for bandwidth-limited channels. Information transmission close to fundamental limits is enabled in this way. However, this only holds for large block ...

Digital communication system have advanced tremendously over the last decades and yielded applications such as high speed data transfer in LTE. In recent years, new communication scenarios like machine-to-machine systems have evolved. These scenarios demand for highly energy efficient receiver desig...
Abstract
This thesis presents a sophisticated development methodology for LDPC decoders. In the scope of this methodology, different architecture concepts are developed and evaluated, a complete LDPC decoder design space exploration is conducted, and various implementation issues are covered includi...
This dissertation focuses on the decoding of low-density parity-check (LDPC) con-
volutional codes, also known as spatially coupled LDPC (SC-LDPC) codes. These
codes combine the properties of both LDPC block codes (good performance for
long block lengths) and convolutional codes (good performance fo...
The finite-length performance of spatially coupled low-density parity-check (SC-LDPC) codes constructed from protographs is analyzed. The equivalence of peeling decoding (PD) and belief propagation (BP) for LDPC codes over the binary erasure channel (BEC) is examined. Modifying the scheduling for PD...
This book guides readers through the design of hardware architectures using VHDL for digital communication and image processing applications that require performance computing. Further it includes the description of all the VHDL-related notions, such as language, levels of abstraction...
The common property among turbo-like code is that they consist of very simple constituent codes that are connected to each other with random or pseudorandom interleavers. The crucial novelty in these codes is the iterative decoding. This means that the constituent codes are decoded separately, which...
This textbook provides a rigorous mathematical perspective on error-correcting codes, starting with the basics and progressing through to the state-of-the-art. Algebraic, combinatorial, and geometric approaches to coding theory are adopted with the aim of highlighting how coding can have an importan...
Optimierung einer Software-Defined-Radio-Plattform am Beispiel des Systems Tower Overlay over LTE-A+
Heutige zellulare Mobilfunknetze erreichen durch die steigende Nachfrage nach Videodiensten ihre Kapazitätsgrenzen. Statt einer Nutzer-individuellen Unicast-Übertragung, ist die Verwendung von Broadcast-Multicast-Ansätzen und den aus der klassischen TV- und Radio-Rundfunkübertragung bekannten ho...
In the past few decades, the optical communication industry has explored multiple degrees of freedom of the photon, such as time, wavelength, amplitude, phase, polarization, and space, to significantly reduce the cost/bit of data transmission by increasing the capacity per fiber through multiplexing...
