Abstract: In recent trends of VLSI technology the reversible logic has became the major area of research in optimization of area, power and speed constraints. The reversible logic has equal number of ...
The viterbi.dll is one of the workhorses of the QIRX-SDR (https://qirx.softsyst.com) and is responsible for Viterbi- and Reed-Solomon decoding/ error correction. The ...
Clearly, wireless LAN (WLAN) systems are a hot topic in the design community. With 802.11b taking off, and 802.11g and 802.11a coming quickly, much attention has been placed on building WLAN access ...
