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...

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...
Forward error correction is an essential part of digital communication systems. Non-binary low-density parity-check (NB-LDPC) codes have an excellent communications performance for short block lengths. The higher the field size is, the better the communications performance is. Non-binary LDPC codes can outperform all other state-of-the-art code classes. However, the algorithmic decoding complexity...
Ultra Wide Band (UWB) systems are designed for short range transmission with very high throughput demands (480 Mbit/s). Current UWB systems specify convolutional codes (CC) for channel coding. However, it was already shown that more sophisticated Low-Density Parity-Check Codes (LDPC) can outperform CC. This gain of communications performance comes with the penalty of a higher implementation complexity...
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...
