Robert Heath, Texas ECE professor, has received the European Association for Signal Processing (EURASIP) 2017 Technical Achievement Award for Significant Contributions to Signal Processing in MIMO Communication Systems. EURASIP serves to further the efforts of researchers by providing a learned and professional platform for dissemination and discussion of all aspects of signal processing.
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 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.
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 use special ADC structures like a time interleaved ADC (TI-ADC) architecture where a number of low-speed, high-precision ADCs operate in parallel.
