In the mobile reception of OFDM, reception characteristics are degraded by ICI(inter-Carrier Interference). In ISDB-T, convolutional code and Reed-Solomon code as error-correcting codes are used. In this paper, decoding and encoding of the error-collecting code are operated in the iterative detection. As the results, it is possible to improve the characteristics.

from a liquid crystal display (LCD) to a camera-equipped mobile device. In this system, two-dimensional
Orthogonal Frequency Division Multiplexing (OFDM) with Quadrature Phase Shift Keying (QPSK) is used
to generate information embedded images shown on the display. In this paper, usage of pilot signals is
investigated for the purpose of improving reliability of the system.

Autonomous robots are becoming widespread and expanding their applications. For such robots, it's necessary to understand the shape of surrounding objects and the position of obstacles precisely by range sensors such as 3D Vision Sensor. When measuring distance by 3D Vision Sensor, the problem is the measurement error caused by secondary reflection light and transmitted light. We studied a method for suppressing measurement error by using additional projection patterns with thin bright bars.

An 8K 120 Hz image capturing experiment using a 133-Mpixel 60 Hz CMOS image sensor is described. To
acquire an 8K 120 Hz image, 2:1 inter-line scanning and interpolation technique with adaptive noise reduction were adapted.
Experimental results show the motion blur was improved and the resolution in the motionless area maintained compared with that
of the conventional 60 Hz scanning. The signal-to-noise ratio was improved 4.4 dB by the adaptive noise reduction technique.

We implemented an IoT sensor for evaluating comfortability of real estate. The IoT sensor can measure temperature, humidity, illuminance, smell and acceleration, and record sound and video. From the experiment in which we set one sensor in northern and southern rooms respectively, we succeeded in visualizing that the room temperatures were very different even in the same building. From the outdoor experiment, we could measure how the vibration and noise were detected in each place.

A novel sampling strategy suitable for compressed sensing MRI (CS-MRI) is proposed. Spatial resolution of
reconstructed images is sometimes reduced due to variable density random undersampling. To improve spatial resolution in CSMRI,
oblique scanning in k-space for the read-out direction is adopted to acquire a higher spatial frequency for the phaseencoding
direction. Reconstruction experiments showed that spatial resolution can be improved without lengthening scan time.

The experimental results using 1,958 videos in Schoo showed that the matrix factorization is the best (precision was 0.28@10), followed by collaborative filtering. On the other hand, content-based filtering did not work well for lecture recommendation.

We propose a method to estimate a position of a light source by using a single RGB-D image. First, highlights on

are computed from normal vectors of the detected highlights and viewing vectors. Finally, the intersection of light vectors is
calculated for estimating a three-dimensional position of the light source.
