Toward Millimeter-Wave Joint Radar Communications: A Signal Processing Perspective

Design Challenges of Millimeter Wave Communications: A MAC Layer Perspective

As the spectrum is becoming more scarce due to exponential demand of formidable data quantities, the new millimiterwave (mmW) band is considered as an enabling player of 5G communications to provide multi-gigabits wireless acccess. MmW communications exhibit high attenuation and blockage, directionality due to massive beamforming, deafness, low-interference, and may need micro waves networks fo...

Combining Millimeter-Wave Radar and Communication Paradigms for Automotive Applications: A Signal Processing Approach (106)

As driving becomes more automated, vehicles are being equipped with more sensors generating even higher data rates. Radars (RAdio Detection and Ranging) are used for object detection, visual cameras as virtual mirrors, and LIDARs (LIght Detection and Ranging) for generating high resolution depth associated range maps, all to enhance the safety and efficiency of driving. Connected vehicles can u...

Signal Processing of Automobile Millimeter Wave Radar Base on BP Neural Network

In this paper BP neural network is used for signal processing of automobile millimeter wave radar instead of FFT(Fast Fourier Transform). Simulation results show that BP neural network is superior to FFT. FFT has the drawback such as large computation and frequency spectrum leakage. The BP neural network has three layers(one input layer, one hidden layer, one output layer).The network is traine...

Introduction to the Special Issue on Signal Processing for Millimeter Wave Wireless Communications

Terahertz Imaging, Millimeter-wave Radar

The millimeter wave (MMW) band of frequencies extends from 30 GHz to 300 GHz, with some fuzziness on both ends of this spectrum. The terahertz (THz) band extends from about 200 GHz to about 30 THz, despite the fact that the lower frequencies in this range are not strictly 10 Hz or higher. These bands are also variously called submillimeter, far-infrared, and near-millimeter. In recent years, th...
