Adaptive pre-equalization using bidirectional pilot sequences to estimate and feed back amplitude transfer function and chromatic dispersion

We propose an adaptive pre-equalization system that compensates the amplitude transfer function and chromatic dispersion using estimates transmitted from the receiver. Two kinds of pilot sequences are used for estimation and mutual communication.

Reducing energy consumption in microcontroller-based platforms with low design margin co-processors

Advanced energy minimization techniques (i.e. DVFS, Thermal Management, etc) and their high-level HW/SW requirements are well established in high-throughput multi-core systems. These techniques would have an intolerable overhead in low-cost, performance-constrained microcontroller units (MCU’s). These devices can further reduce power by operating at a lower voltage, at the cost of increased sensitivity to PVT variation […]

Estimation of carrier and channel parameters in time-selective fading channels

Assuming a land-mobile satellite link with negligible multipath and shadowing effects, the corresponding channel model is adequately described by a correlated Rician distribution. In this context, the estimation of carrier and channel parameters has been investigated in some earlier work by means of an algorithmic approach primarily based on heuristic considerations. In the current study, […]

PerSEE: A central sensors fusion electronic control unit for the development of perception-based ADAS

Automated vehicles and Advanced Driver Assistance Systems (ADAS) face a variety of complex situations that are dealt with numerous sensors for the perception of the local driving area. Going forward, we see an increasing use of multiple, different sensors inputs with radar, camera and inertial measurement the most common sensor types. Each system has its […]

A verify-correct approach to person re-identification based on Partial Least Squares signatures

In the surveillance field, it is very common to have camera networks covering large crowded areas. Not rarely, cameras in these networks do not share the same field of view and they are not always calibrated. In these cases, common problems such as tracking cannot be directly applied as the information from one camera must be also consistent with […]

CDI Precoding for Massive MIMO

We discuss the benefits of a linear precoding stage based solely on second order information of the channel with application to massive MIMO networks. Specifically, the proposed channel distribution information (CDI) precoding is used to completely suppress the interference caused by pilot contamination, thus leading to a significant gain in spectral efficiency for pilotcontamination limited massive […]

High gain Microstrip Antenna design for 2.4GHz WLAN application

IEEE 802.11x standard widely used in wireless local area network systems is called Wi-Fi as well. In this study high gain Microstrip Antenna (MA) design is presented for 2.4 GHz WLAN application. Simulations were made on parameters such as the geometry and size of antennas, type of dielectric material, the thickness of substrate for most appropriate designing […]

Hierarchical hybrid testability modeling and evaluation method based on information fusion

In order to meet the demand of testability analysis and evaluation for complex equipment under a small sample test in the equipment life cycle, the hierarchical hybrid testability modeling and evaluation method (HHTME), which combines the testability structure model (TSM) with the testability Bayesiannetworks model (TBNM), is presented. Firstly, the testability network topology of complex equipment is built […]

Tight and Compact MIP Formulation of Configuration-Based Combined-Cycle Units

Private investors, flexibility, efficiency and environmental requirements from deregulated markets have led the existence and building of a significant number of combined-cycle gas turbines (CCGTs) in many power systems. These plants represent a complex optimization problem for the short-term planning unit commitment (UC) carried out by independent system operators due to their multiple operating configurations. […]
