Non-ideal space division multiple access and its application None

Ji-ying XIANG

Frontiers of Information Technology & Electronic Engineering 2018, Volume 19, Issue 3, Pages 357-366 doi: 10.1631/FITEE.1700827

Abstract: We study the performance of space division multiple access (SDMA) under a non-ideal engineering situationAs the channel measuring is always non-ideal, we use two methods, feedback mode and non-feedback modeIt is proposed that the non-feedback mode is preferable even for some non-reciprocal channels.

An autonomous miniature wheeled robot based on visual feedback control

CHEN Haichu

Frontiers of Mechanical Engineering 2007, Volume 2, Issue 2, Pages 197-200 doi: 10.1007/s11465-007-0033-7

Abstract: Using two micro-motors, a novel omni-direction miniature wheeled robot is designed on the basis of the bi-corner driving principle. The robot takes advantage of the Bluetooth technology to wirelessly transmit data at a short distance. Its position and omni-direction motion are precise. A Charge Coupled Device (CCD) camera is used for measuring and for visual navi gation. A control system is developed. The precision of the position is 0.5 mm, the resolution is about 0.05 mm, and the maximum velocity is about 52 mm/s. The visual navigation and control system allow the robot to navigate and track the target and to accomplish autonomous locomotion.

Keywords： measuring distance autonomous locomotion advantage navigation
