Low-Power Fully Digital Transceivers
The millimeter wave (mmWave) bands, roughly between 30 and 300 GHz, are an attractive candidate for next-generation cellular systems due to the vast quantities of spectrum and the potential for exploiting very high-dimensional antenna arrays. However, a significant issue in realizing these systems is power consumption, particularly in handheld mobile devices. In addition to the high power consumed baseband processing, one critical concern is the power consumption in the analog-to-digital (ADC) and digital-Analog (DAC) conversions due to the need to process large number of antenna outputs and very wide bandwidths. This project is currently investigating two technologies for reducing power consumption in ADCs for mmWave systems: Use of very low-resolution fully digital transceivers for cellular control plane signaling. Our initial results suggest that in mobile, multi-user scenarios, low-resolution architectures can offer significant gains for directional search and multiple access with minimal increase in power. Develop a preliminary high-level design for a hypothetical low-resolution fully digital mmWave front end. This will evaluate different design choices for the A/D and D/A. Circuit simulation will be used for power and area estimation. After the system level design and optimization, a prototype ASIC will be fabricated in submicron CMOS technology. Joint optimization of bandwidth, quantization resolution and beamforming architecture choices under ADC power constraints. This work has demonstrated that the choice of beamforming architectures depends critically on the ADC power limits. In addition, under ADC power limits, throughput may not be maximized at very wide bandwidths suggesting multi-user scheduling may be necessary to fully realize the potential of mmWave bands.
