Submillimeter wave communication versus millimeter wave communication

This paper studies the performance of a submillimeter wave antenna operating between frequencies 0.1 THz and 10 THz with a 4-cyano-4-pentylbiphenyl [5CB] substrate. Since the size and shape of the antenna impact its gain/directivity, resonant frequency, bandwidth, and efficiency, the two antenna types considered in this paper are: (a) Rectangular Patch Antenna (RPA), and (b) Cylindrical Dielectric Resonator Antenna (CDRA). Here a submillimeter wave antenna is compared with a millimeter wave (a few GHz to 100 GHz) antenna. These popular mm-wave antennas are chosen for the submillimeter wave antenna in order to understand changes in their performance as the result of changes in their geometrical shape. FEldberechnung bei Korpern mit beliebiger Oberflache (FEKO) software is used for the design and calculation of the Three-Dimensional (3D) ElectroMagnetic (EM) patterns. This paper also concentrates on the design and analysis of a massive submillimeter wave Multiple-Input Multiple-Output (MIMO) (8 by 8) RPA and CDRA.

HDTV communication systems in broadband communication networks

Two high-definition television (HDTV) communication systems created for broadband communication networks are discussed. Nationwide HDTV transmission and distribution services and HDTV subscriber distribution services are examined. A network architecture for high-quality HDTV transmission is described. The transmission bit rates of HDTV services, which are the basic factors in constructing the network frame, are considered. Two HDTV coding algorithms, subband discrete cosine transform (DCT) and subband differential pulse-code modulation (DPCM) are described, and their coding bit rates discussed. A synchronous-digital-hierarchy-based synchronous transfer mode network design suitable for the transmission of HDTV signals in broadband communication networks are described     

Context-aware communication

This article describes how the changing information about an individual's location, environment, and social situation can be used to initiate and facilitate people's interactions with one another, individually and in groups. Context-aware communication is contrasted with other forms of context-aware computing, and we characterize applications in terms of design decisions along two dimensions: the extent of autonomy in context sensing and the extent of autonomy in communication action. A number of context-aware communication applications from the research literature are presented in five application categories. Finally, a number of issues related to the design of context-aware communication applications are presented.     

Proximity communication

This paper reports results from wireless chip-to-chip communication experiments. Sixteen bit words pass from one chip to another in parallel without detectable error at 1.35 billion data items per second for a total data rate of 21.6 Gigabits per second. The experiment transmits pseudo random patterns between chips built in a 350-nm CMOS technology. Chips touch face-to-face to communicate. The same pseudorandom data pattern is loaded onto both chips so that the receiving chip can check the accuracy of every bit communicated. Each communication channel consumes a static power of 3.6 mW, and a dynamic power of 3.9 pJ per bit communicated. The channels lie on 50-/spl mu/m centers. Because the capacitive communication works through covering oxide, ESD protection is unnecessary. Vernier position measuring circuits built into the chips indicate the relative position of transmitting and receiving arrays to assist mechanical alignment. The test chip includes a Vernier measurement circuit that provides inter-chip position measurements with a resolution of 1.4 /spl mu/m.     

Multimedia communication

Multimedia communication deals with the transfer, protocols, services, and mechanisms of discrete media data (such as text and graphics) and continuous media data (like audio and video) in/over digital networks. Such a communication requires all involved components to be capable of handling a well-defined quality of service (QoS). The most important QoS parameters are used to request: (1) the required capacities of the involved resources, (2) compliance to end-to-end delay and jitter as timing restrictions, and (3) restriction of the loss characteristics. In this paper, we describe the necessary issues and study the ability of current networks and communication systems to support distributed multimedia applications. Further, we discuss upcoming approaches and systems that promise to provide the necessary mechanisms and consider which issues are missing for a complete multimedia communication infrastructure     

Chaotic communication

This paper reports how European researchers were able to use the chaos phenomenon to send digital messages at gigabit per second speeds over 115 km of commercial optical fiber beneath the streets of Athens, Greece. A distinct advantage of chaotic communication is that it is often easier to generate robust, high-power chaotic signals than conventional ones. A chaotic signal is also harder for an eavesdropper to identify because it is difficult to distinguish from background noise.     

Eigenvalue communication

The authors propose a communication method for a nonlinear and dispersive medium such as an optical fiber that is based on eigenvalues of associated equations for the wave amplitude. In optical communications, the communication distance measured by the carrier wavelength reaches the order of 10/sup 11/-10/sup 13/. As a result, dispersive and nonlinear effects, even if small, contribute significantly to the distortion of signal information contained in waveforms or in frequency spectra. Thus, it is desirable to use other parameters which remain unaltered. The eigenvalues of the associated equation for the nonlinear Schrodinger equation which describes the lightwave envelope in fibers constitute such parameters. Soliton-based communication corresponds to the case of one eigenvalue.<>
