Early Bird Discount Registration Now Available for TWS 2016

On October 18, 2016, Texas Wireless Summit (TWS) will explore how automated vehicles will re-shape wireless over the next 10 years with their demands for coordinated sensing and decision-making. Reshaping Wireless through Automated Vehicles will look at the benefits and requirements of connectivity, the key challenges of vehicle sensing and shared data analytics, including lightly-processed radar, lidar and camera data. 

Analyzing Uplink Massive MIMO Using Stochastic Geometry

Massive multiple-input multiple-out (MIMO) is a promising technique for 5G cellular networks. Prior work showed that high throughput can be achieved with a large number of base station antennas through simple signal processing in massive MIMO networks. The performance of massive MIMO in a large-scale network with irregular base station locations and random user distributions is not yet fully understood.

Dynamic Subarrays for Hybrid Precoding in Wideband mmWave Massive MIMO Systems

Hybrid analog/digital precoding can potentially achieve high spectral efficiencies while requiring less cost and power consumption than fully-digital solutions. This makes it an attractive candidate architecture for millimeter wave systems, which requires deploying large antenna arrays at both the transmitter and receiver to guarantee sufficient received signal power. Most of prior work though on hybrid precoding focuses on narrow-band channels and assumes a fully-connected hybrid architecture. MmWave systems, though, are expected to employ wideband with frequency selectivity.

Forward Collision Vehicular RADAR with IEEE 802.11

The majority of automotive radar deployed in vehicles operates at the millimeter wave (mmWave) band. These devices, however, are susceptible to multiple security risks such as spoofing, which has severe implications for vehicular functions such as forward collision detection and avoidance. The project by Prof. Robert Heath Jr., former UT Research Scientist Dr. Bob Daniels, and student Enoch Yeh introduces a concept for enabling radar functions on traditional IEEE 802.11 devices, creating a joint framework for radar and communications.

Frequency Selective Hybrid Precoding in Millimeter Wave OFDMA Systems

Hybrid precoding, a combination of analog and digital precoding, is an attempt to reach a compromise between complexity and performance. By exploiting more than one radio frequency chain, hybrid precoding enables a millimeter wave (mmWave) system to take advantage of both spatial multiplexing and beamforming gain. A major challenge with hybrid precoding is its configuration in wideband systems because the analog beamforming weights should be the same across the entire band.

Initial Beam Association in Millimeter Wave Cellular Systems: Analysis and Design Insights

Wireless communication via millimeter wave (mmWave) frequencies is a key component of future cellular systems. mmWave deployments will use beamforming with large antenna arrays by both the base stations and mobile stations to ensure sufficient received signal power. Prior work on coverage and rate of mmWave cellular networks focused mainly on the case when base stations and mobile users beamfomring vectors are perfectly designed for maximum beamforming gains.
