This contribution describes design methodology and implementation of a single-chip timing and carrier synchronizer and channel decoder for digital video broadcasting over satellite (DVB-S). The device consists of an A /D converter with AGC, timing and carrier synchronizer with matched filter, Viterbi decoder including node synchronization, byte and frame synchronizer, convolutional de-interleaver, Reed Solomon decoder, and a descrambler.The system was designed in accordance with the DVB specifications. It is able to perform Viterbi decoding at data rates up to 56 Mbit /s and to sample the analog input values with up to 88 MHz. The chip allows automatic acquisition of the convolutional code rate and the position of the puncturing mask. The symbol synchronization is performed fully digitally by means of interpolation and controlled decimation. Hence, no external analog clock recovery circuit is needed.For algorithm design, system performance evaluation, co-verification of the building blocks, and functional hardware verification an advanced design methodology and the corresponding tool framework are presented which guarantee both short design time and highly reliable results. The chip has been fabricated in a 0.5 µm CMOS technology with three metal layers. A die photograph is included.

The Japanese leaf flea, the natural enemy of the Japanese knotweed, has survived the Dutch winter and can be used to combat the invasive plant, researchers of Leiden University’s Biology Institute have found. The leaf fleas (aphalari itadori), which feed on the sap knotweed buds need to grow, were let loose in three trial locations in October last year. Not only did they attack the knotweed, they also multiplied. ‘It is very important that they did because we need a...

Our thought lives have incredible power over our mental, emotional, and even physical well-being. In fact, our thoughts can either limit us to what we believe we can do or release us to experience abilities well beyond our expectations. When we choose a mindset that extends our abilities rather than placing limits on ourselves, we will experience greater intellectual satisfaction, emotional control, and physical health. The only question is . . . how? Backed by up-to-date scientific research and biblical insight, Dr. Caroline Leaf empowers readers to take control of their thoughts in order to take control of their lives. In this practical book, readers will learn to use - The 5-step Switch on Your Brain Learning Program, to build memory and learn effectively - The Gift Profile, to discover the unique way they process information - The Mindfulness Guide, to optimize their thought life and find their inner resilience Dr. Leaf shows readers how to combine these powerful tools in order to improve memory, learning, cognitive and intellectual performance, work performance, physical performance, relationships, emotional health, and most importantly a meaningful life well lived.
