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...
Towards a design framework for heterogeneous Wireless Sensor Networks
Wireless Sensor Networks consist of resource-constrained (energy, memory and processing) sensor nodes that are deployed at different locations, in order to monitor physical or environmental conditions. Several limitations exist nowadays, at...
On the discussions of diversity combination in multiuser cooperative networks
In multiuser cooperative networks, cooperative diversity can be obtained by the help of relays, whereas multiuser diversity is an inherent diversity exploited by properly designed multiuser scheduling algorithms. In this paper, we introduce...
Mobile robot deployment based on Voronoi diagram
This paper describes a new method for deployment of wireless relay nodes. When applying rescue robots in building or underground city, the wireless radio is attenuated significantly, thus multi-hop extension by relay of wireless communicati...
Detection of number of uncorrelated and coherent narrowband signals with L-shaped sensor array
This paper deals with the problem of estimating the number of mixed narrowband signals of uncorrelated and coherent signals impinging on the L-shaped sensor array, which is structured by two uniform linear arrays (ULAs). Since the total num...
Design of ball-cage based miniature stroke for integration in a flexible actuator with thrust wire
Robotic technology is used widely today because of their advantages to support human operator. Robot systems have been used, not only for industrial processes, but also for a wide range of applications, such as minimally invasive surgery. T...
A method for estimation of operational torque with utilizing a hysteresis model
Along with the population aging, human interactive robots are expected to be introduced in our daily lives especially in developed countries. For such robots, bilateral control is widely researched as a technique for transmission of both po...
