The Monte CarloMonte Carlo method is state-of-the art to verify the performance of wireless communication systems. Statistical simulationssimulations for various signal-to-noise (SNR) operation points are mandatory. Bit error rates (BERs) of 10−9 or even lower require the simulationsimulation of tens to hundreds of thousands of blocks for a single SNR operating point. Therefore, system simulationsimulation...

Future mobile and wireless communication networks require flexible modem architectures to support seamless services between different network standards. Hence, a common hardware platform that can support multiple protocols implemented or controlled by software, generally referred to as software defined radio (SDR), is essential. This chapter presents a family of application-specific instruction-set...
Non-binary low-density parity-check codes have superior communications performance compared to their binary counterparts. However, to be an option for future standards, efficient hardware architectures must be developed. State-of-the-art decoding algorithms lead to architectures suffering from low throughput and high latency. The check node function accounts for the largest part of the decoders overall...

In modern communication systems the required data rates are continuously increasing. High speed transmissions can easily generate throughputs far beyond 1 Tbit/s. To ensure error free communication, channel codes like Low-Density Parity Check (LDPC) codes are utilized. However state-of-the-art LDPC decoders can process only data rates in the range of 10 to 50 Gbit/s. This results in a gap in decoder...
The design of double-iterative systems like turbo synchronization or iterative demapping and decoding will be one of the big challenges in the next years. The components of such systems need to fulfill stringent conditions on throughput and flexibility thus making a reuse of available standard components difficult. We present a high throughput ASIC design for LDPC decoding in iterative MIMO systems...
The upcoming WiMedia 1.5 standard for Ultra-Wideband (UWB) supports payload throughputs of more than 1 Gbit/s. It features Low-Density Parity Check (LDPC) codes as coding scheme for the high data rate modes. LDPC decoder design for this standard is a very challenging task, since it has to offer high throughputs, low latency, excellent error correction capabilities, and furthermore flexibility.
In this paper the authors present an enhanced channel coding scheme and architecture providing LDPC codes for the use in future generations of the WIMEDIA UWB industry standard. Main emphasis is put on the development of a low complex LDPC code which provides a throughput of at least 1.1 Gbit/s, with a reduced number of iterations even up to 1.6 Gbit/s. By using such an enhanced channel coding scheme...
