Advanced coding techniques for few mode transmission systems [PDF]
, 2015 We experimentally verify the advantage of employing advanced coding schemes such as space-time coding and 4 dimensional modulation formats to enhance the transmission performance of a 3-mode transmission system.

Novel infinitely Variable Transmission allowing efficient transmission ratio variations at rest
2015 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2015 Recent studies showed that Continuously Variable Transmissions (CVT) and Infinitely Variable Transmissions (IVT) can considerably improve the locomotion efficiency in legged robot. A CVT is a transmission whose ratio can be continuously varied and an IVT is a transmission whose ratio can be continuously varied from positive to negative values. However,

Double pulse transmission - signal-to-noise ratio improvement in ultrasound imaging
Archives of Acoustics, 2008 This study investigates a new composing method of double transmission of short coded sequences based on well-known Golay complementary codes, which allow to obtain the higher signal-to-noise ratio (SNR) and increase penetration depth. The
