New High Performance Deterministic Interleavers for Turbo Codes
Advances in Electrical and Computer Engineering, 2010 Turbo codes offer extraordinary performance, especially at low signal to noise ratios, due to a low multiplicity of low weight code words. The interleaver design is critical in order to realize an apparent randomness of the code, thus further enhancing

Systemic bio‐inequity links poverty to biodiversity and induces a conservation paradox
People and Nature, EarlyView.Abstract Biodiversity is declining globally while inequity is growing, and poverty rates are not improving. Global sustainable development and conservation initiatives aim to address biodiversity loss and poverty simultaneously. Through text analysis of global biodiversity policies, we identified a consistent narrative that countries with high ...
