Enhanced Channel Coding for OFDM-based UWB Systems

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 the range or the data rate of the WIMEDIA UWB system could be remarkably increased with a limited increase in implementation complexity with respect to silicon area
