Robust MVDR beamforming using the DOA matrix decomposition
The minimum variance distortionless response (MVDR) beamformer is very sensitive to errors, such as the the finite snapshots and the steering vector errors. A small mismatch can lead to serious degradation to its performance, especially at ...
Direction estimation of uncorrelated and coherent narrowband signals with uniform linear array
In this paper, an effective direction-of-arrival (DOA) estimation method is proposed with a uniform linear array (ULA) when uncorrelated and coherent signals coexist. The direction-of-arrivals (DOAs) of uncorrelated signals and coherent sig...
Cost-efficient built-in repair analysis for embedded memories with on-chip ECC
This paper concerns low-cost implementation of built-in repair analysis (BIRA) for embedded memories. As embedded memories become more and more dominant in system-on-chip (SoC) design, it is very crucial to achieve sufficiently high embedde...
A power scalable SAR-ADC in 0.18µm-CMOS with 0.5V nano-watt operation
This paper presents an extremely low-power and low-voltage Analog-to-Digital Converter (ADC) for wireless sensor networks or medical implantable devices. Top plate sampling and bootstrap switch are used to realize ultra low-voltage (0.5V) o...
