212 results about "Small cell" patented technology

Small cells are low-powered cellular radio access nodes that operate in licensed and unlicensed spectrum that have a range of 10 meters to a few kilometers. They are "small" compared to a mobile macrocell, partly because they have a shorter range and partly because they typically handle fewer concurrent calls or sessions. They make best use of available spectrum by re-using the same frequencies many times within a geographical area. Fewer new macrocell sites are being built, with larger numbers of small cells recognised as an important method of increasing cellular network capacity, quality and resilience with a growing focus using LTE Advanced.

Pi-type trench gate silicon carbide mosfet device and fabrication method thereof

The disclosure relates to a π type trench gate silicon carbide MOSFET device and a fabrication method thereof. To protect a trench gate oxide layer without increasing a channel resistance and process complexity, a second conductivity type of heavily doped deep well inserted with double gate trenches along the sidewalls of deep well is designed. The deep well is connected to the source metal directly. The electric potential is clamped to the source during the voltage blocking and turn-off state, which reduces the electric field in the gate oxide and reduces the miller capacitance. An interlayer dielectric layer is deposited above the conductive dielectric polysilicon layers and extends outward separately to cover a part of the source region. A smaller cell pitch can be achieved by controlling the spacing between the first and the second trench gate, thereby increasing the channel density and reducing the channel resistance.

Chaotic image encryption method based on improved Josephus transform and Knight's Tour joint scrambling

This paper proposes a chaotic image encryption method based on the combined scrambling of the improved Josephus transform and the Knight's Tour. First, a chaotic pseudo-random integer sequence is generated and integerized using a memristive chaotic system. Then, the pixel matrix is ​​divided into several small cell pixel matrices. Within each cell pixel matrix, the chaotic pseudo-random integer sequence is used to control the counting starting point, counting period, and counting direction, respectively. Block scrambling is performed using the improved Josephus scrambling algorithm. Subsequently, each cell pixel matrix after the improved Josephus block scrambling is treated as a checkerboard point, and the direction of the Knight's Tour is controlled using the chaotic pseudo-random integer sequence. The image is scrambled using the improved Knight's Tour algorithm and the improved Josephus scrambling algorithm, effectively reducing the correlation between adjacent pixels in the scrambled image and improving the global encryption effect of the image. Finally, the chaotic pseudo-random integer sequence generated and integerized by the memristive chaotic system is used to diffuse the pixels, enhancing the security of the encrypted image.
