In this letter, we propose a deep learning-based spreading sequence design and active user detection (AUD) to support massive machine-type communications (mMTC) where a large number of devices access the base station using non-orthogonal spreading se

This correspondence paper addresses linear precoding design for sum rate maximization in low-latency orthogonal frequency-division multiplexing systems. In order to mitigate the overhead of cyclic prefix (CP) originating from shortened symbol duratio

Very low latency is one of the key requirements of 5G wireless access. To reduce latency in orthogonal frequency division multiplexing (OFDM) systems while not increasing the overhead, it is of primary importance to reduce the effective delay spread

In this paper, we propose a novel method to jointly estimate the activities and channel coefficients of devices in massive machine-type communications (mMTC) systems. We formulate a maximum a posteriori probability (MAP) estimation problem by exploit

In this paper, we developed a low-cost video-oculography device that diagnose neural diseases such as nystagmus by the vestibular function test using an infrared camera. An infrared camera and LEDs were attached in a pair of developed goggles, which
