The demand for wireless data is predicted to grow exponentially in the next few years, driven by the growing popularity of smartphones and tablet devices, and new data intensive services.
We describe a new method of protecting dpcm (differential pulse code modulation) speech signals against the effects of transmission errors.
We demonstrate a novel multiple-path DPSK detection scheme requiring only a few simple logic gates, This scheme is shown to provide 0.4dB enhancement in back-to-back received sensitivity and 0.85 d
This letter compares pilot-aided phase-shift keyed (PSK) and differential PSK (DPSK) modulation when using new maximum a posteriori joint channel estimation and equalization receivers with frequenc
S mentioned in the preceding article by Dr. Jewett, the first and second of the three following memoranda were the basis of methods of designing transpositions for voice-frequency circuits.

The overall target of the EARTH project is to reduce the power consumption of mobile broadband networks by 50% with preserved quality of service.
It has long been known that hydrophobic surfaces with roughness features of an appropriately chosen length scale interact with water in a highly non-wetting manner.
The design and performance of a new type high resolution, high transmission soft x-ray monochromator are presented.
Path-planning algorithms are currently an active research area.
