Optimal configuration of digital communication network
As the costs for maintaining computer communication networks are rapidly rising, it is particularly important to design the network efficiently. The objective of this thesis is to model the minimum cost design of digital communications networks and propose a heuristical solution approach to the …

Modulation classification of digital communication signals
Modulation classification of digital communications signals plays an important role in both military and civilian sectors. It has the potential of replacing several receivers with one universal receiver. An automatic modulation classifier can be defined as a system that automatically identifies the …

Digital Communication Technologies in Romantic Relationships
This thesis explores the use of ‘Digital Communication Technology’ (DCT) devices within committed monogamous romantic relationships through the analysis of forty-five semi-structured interviews. I argue that too often contemporary researchers are taking sides that the manner in which mobile devices …

Digital communication networks incorporating mobile data terminals
The use of digital communication systems is increasing very rapidly. This is due to lower system implementation cost compared to analogue transmission and at the same time, the ease with which several types of data sources (data, digitised speech and video, etc.) can be mixed. The emergence of …

Generalized Data-Aided Equalizers for Digital Communication Channels
Although, the ACE structure has advantages in implementations of pipelined structure and canceller structure, we found that the performance of the ACE depends on the channel characteristics. Comparing the ACE with the DFE, the performance of the ACE is not always better than the performance of the …

Pulse-based ultra-wideband transmitters for digital communication
… since the 1950's; however, in 2002 the Federal Communications Commission approved the use of the 3.1-10.6GHz band for unlicensed UWB applications. The restriction on transmitted power spectral density in this band is equal to the noise emission limit of household digital electronics. This band …

Detector design and estimation for a digital communication system
This thesis investigates the behavior of two digital communication systems based on Moving-Average Matched Filters (MAMF). In general, matched filters are instrumental in detecting signals corrupted by noise as they are designed to maximize the probability of detection of the transmitted signals. …

Synchronization in digital communication systems: performance bounds and practical algorithms
Communication channels often transfer signals from different transmitters. To avoid interference the available frequency spectrum is divided into non-overlapping frequency bands (bandpass channels) and each transmitter is assigned to a different bandpass channel. The transmission of a signal over a …
