Digital communication system design

This paper presents a designing and implementing circuit of wireless charging of the parking management system based on Radio frequency identification (RFID) technique and STM32F103 as the control kernel. The advantage of digital modulation technique in applied radio signals is used to identify specific targets and read-write relevant data. Communication is established between the parking space reader and the onboard responder.

This paper presents the research on design and control of Remotely Operated Vehicle (ROV) belonging to National key Laboratory of Digital Control and System Engineering. Basically, it is controlled by human pilots to move underwater and perform specifically pre-assigned tasks. T he power supply and communication channel for the vehicle are connected from an onshore station via cable systems. There are several stages of the pipeline in implementing a full-scale ROV platform that must be studied carefully.

Digital broadcast systems have increasingly been deployed for various services such as Digital Video Broadcasting (i.e. DVB-S, DVB-T, etc.) and Digital Audio Broadcasting (DAB). Classical digital broadcast systems were designed with fixed modulation guarantee reliable communication even with very hostile channel environment. DVB-T2 terrestrial television standard is becoming increasingly important. The emergence of it is motivated by the higher spectral efficiency and adopting transition from analogue TV to DVB-T2, or transition from DVB-T to DVB-T2.

Hybrid analog and digital beamforming (HBF) has recently emerged as an attractive technique for millimeter-wave (mmWave) communication systems. It well balances the deman d for sufficient beamforming gains to overcome the propagatio n loss and the desire to reduce the hardware cost and power consumption. In this paper, the mean square error (MSE) is chosen as the performance metric to characterize the transmission reliability. Using the minimum sum-MSE criterion, we investigate the HBF design for broadband mmWave transmissions.

The potential of using of millimeter wave (mmWave) frequency for future wireless cellular communication systems has motivated the study of large-scale antenna arrays for achieving highly directional beamforming. However, the conventional fully digital beamforming methods which require one radio frequency (RF) chain per antenna element is not viable for large-scale antenna arrays due to the high cost and high power consumption of RF chain components in high frequencies.

Over the past years, a number of international initiatives that recognize the importance of sharing and reusing digital educational resources among educational communities through the use of Learning Object Repositories (LORs) have emerged. Typically, these initiatives focus on collecting digital educational resources that are offered by their creators for open access and potential reuse. Nevertheless, most of the existing LORs are designed more as digital repositories, rather than as Knowledge Management Systems (KMS).

Learning Object Repositories (LORs) are a core element of the Opening up Education movement around the word. Despite, the wide efforts and investments in this topic, still most of the existing LORs are designed mainly as digital libraries that facilitate discovery and provide open access to educational resources in the form of Learning Objects (LOs). In that way, LORs include limited functionalities of Knowledge Management Systems (KMSs) for organizing and sharing educational communities’ explicit and tacit knowledge around the use of these educational resources.

From a system’s perspective, the design of the Sense- Less system is to a large extent governed by constraints that are unique to white spaces. We show that any white space system in which, instead of sensing, devices rely on a third-party entity to learn about white space availability must follow certain design principles. Specifically, we show that in order to achieve sufficiently accurate (i.e., not overly conservative) prediction of white space availability, sophis- ticated and computationally-intensive models must be used.

Another class of linear codes, known as Convolutional codes. We study the structure of the encoder. We study different ways for representing the encoder.Convolutional codes offer an approach to error control coding substantially different from that of block codes. A convolutional encoder: encodes the entire data stream, into a single codeword. does not need to segment the data stream into blocks of fixed size (Convolutional codes are often forced to block structure by periodic truncation). is a machine with memory.

From a more pragmatic standpoint, graphics concepts that are important in image analysis include light models for illumination and reflection, geometrical transformations, contours and surface approximation, algorithms for region delineation, and, of particular importance in 3D medical imaging, geometrical modelling. Another joint area of interest is in hardware and software, with a common trend towards the use of RISC processors, parallel computation, color devices, etc.
