MIMO
Resolution-Adaptive Hybrid MIMO Architectures for mmWave Communication
Moving to a millimeter wave (mmWave) spectrum in range of 30-300 GHz enables the utilization of multi-gigahertz bandwidth and offers an order of magnitude increase in achievable rate. The small wavelength allows a large number of antennas to be packed into transceivers with very small antenna spacing. Leveraging the large antenna arrays, mmWave systems can manipulate directional beamforming to produce high beamforming gain, which helps overcome large free-space pathloss of mmWave signals.

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.
Prof. Robert Heath Part of Team Selected as Finalist for European Inventor Award
Prof. Robert Heath is part of a team that was selected as one of three finalists for the prestigious European Inventor Award in the Non-European Countries category. Robert was part of the team led by his PhD advisor Prof. Arogyaswami Paulraj of Stanford University that was recognized for its contributions to Faster Wireless Connectivity (MIMO). Robert and his team are in very good company: another finalist this year is Bob Langer, MIT, who is well-known for his contributions to biotechnology and for arguably being the most successful serial academic entrepreneur.
Channel Estimation in Millimeter Wave MIMO Systems with One-Bit Quantization
Millimeter wave (mmWave) is a technology that can provide high bandwidth communication links in cellular systems. As mmWave uses larger bandwidths, the corresponding sampling rate of the analog-to-digital converter (ADC) scales up. Unfortunately, high speed, high resolution (e.g., 6-12 bits) ADCs are costly and power-hungry for portable devices. A possible solution is to live with ultra low resolution ADCs (1-3 bits), which reduces power consumption and cost.

As mmWave uses larger bandwidths, the corresponding sampling rate of the analog-to-digital converter (ADC) scales up. Unfortunately, high speed, high resolution (e.g., 6-12 bits) ADCs are costly and power-hungry for portable devices. A possible solution is to use special ADC structures like a time interleaved ADC (TI-ADC) architecture where a number of low-speed, high-precision ADCs operate in parallel.
