System design principles and high-level design details are described for a new spreadspectrum radio design for the 900 MHz. Amateur band. The radio is designed to provide a 10-base-T interface as the data port, and is designed to provide transport of IP-based data. It is planned to provide both stand-alone and fully-networked hub configurations. The design is based on Frequency-Hopped Spread Sp...

Robustness is the key attribute of Spread Spectrum (SS) watermarking scheme. Several SS image watermarking algorithms have been proposed for multimedia signals but very few works have taken into consideration the issues responsible for robustness improvement. The current paper has critically analyzed few such factors namely properties of spreading codes, proper signal decomposition suitable for...

The Federal Communications Commission (FCC) has used auctions to award spectrum since 1994. During this time period, the FCC has experimented with a variety of auctions rules including click box bidding and anonymous bidding. These rule changes make the actions of bidders less visible during the auction and also limit the set of bids that can be submitted during a particular round. Economic the...

The 2010 German 4G spectrum auction was an unusually large simultaneous ascending multi-band auction. The bidding was competitive, the final assignment was efficient and the revenue was close to expectations. However, our analysis suggests that, theoretically, independent and rational bidders had an opportunity to implicitly coordinate on a low-revenue outcome. Yet, the same analysis suggests t...

In evaluations of Spectrum with designers, while all were committed to the notion of PX, not everyone was able to translate from emotions into playable scenarios, particularly when those emotions were either visceral in nature or unusual within existing games. In evaluations with players, participants sometimes struggled to fit emotionally-specific language around their game experiences, but al...

The paper introduces and describes the spectrum-based design of RBF neural networks. The RBF neural networks used in the paper work with damped sinusoidal nonlinear activation functions. The concept of the associated spectrum of the data is introduced and it is shown how to apply this spectrum to find the number and internal parameters of hidden neurons for a neural network solution of the rela...

Macrosomia is associated with considerable neonatal and maternal morbidity. Factors that predict macrosomia are poorly understood. The increased rate of macrosomia in the offspring of pregnant women with diabetes and in congenital hyperinsulinaemia is mediated by increased foetal insulin secretion. We assessed the in utero and neonatal role of two key regulators of pancreatic insulin secretion ...

Spread spectrum communication technology, compared with the conventional communication technology, has many characteristics, such as a low interception rate, strong anti-noise performance, noise immunity, information hiding and multiple access communication. Widely used in military communication and civil communication at present, it is the core technology in the third generation mobile communi...

ATPG vectors for a combinational circuit exhibit correlations among the bits of a test vector. We propose a BIST/decompressor circuit design methodology using spectral methods which utilizes the correlation information. This circuit serves dual purposes. It generates BIST vectors that are similar to the ATPG vectors with higher test coverage as compared to random and weighted random vectors. Th...
