This paper proposes the fast chirp MIMO radar using Doppler offset orthogonal codes (DO-OCs). The proposed enables Doppler and code division multiplexing. The proposed has two merits. One is that phase modulators to modulate chirp signals is to be si

A single-chip CMOS transceiver (TRX) capable of wireless data rates up to 80 Gb/s using part of frequencies (252–279 GHz) covered by IEEE Std 802.15.3d is presented. The TRX chip operates in either transmitter (TX) or receiver (RX) mode at frequenc

We propose a convolutional neural network (CNN)which classifies the type and direction of a stationary object from the range-Doppler map acquired by a 79 GHz MIMO radar. The multi-class (21 classes)classification is performed by inputting the single

IEEE Standard 802.15.3d, published in October 2017, defines a high-data-rate wireless physical layer that enables up to 100Gb/s using the lower THz frequency range between 252 and 325GHz (hereafter referred to as the “300GHz band”). It stipulates

This paper proposes fast 2D maximum likelihood (ML) angle estimation in order to reduce computational complexity and to enhance 2D angle separation ability. The proposed consists of two steps. The first step is independent 1D ML azimuth/elevation ang
