ABSTRACT Due to tremendous growth of multimedia applications over networks such as the Internet, multimedia traffic causes network congestion, which results into packet loss due to transmission errors resulted by low data transmission reliability. Forward Error Corrections techniques, have been proposed to increase data transmission reliability at the price of bandwidth expansion due to high channel code rates. This is because multimedia files are large in size (in Megabytes), therefore, high...
ABSTRACT This dissertation intends to present various fading problems affecting particularly wireless signal transmission over water and over thick forest and analyze its underlying principles in communication network. The dissertation also investigates various techniques used in practice to mitigate effects of fading over the said terrains. The dissertation is motivated by the fact that mobile companies, Airtel Network in particular, still suffer from fading in their transmission networks de...
ABSTRACT Magnetic induction (MI) is a physical layer technology that is effective for underground wireless communications. The underground communications involve three major communication links, namely underground to underground (UG2UG), underground to aboveground (UG2AG), and aboveground to underground (AG2UG). AG2UG and UG2AG links are special in a sense that they cross two different media, which are soil and free space. While this is the case, the soil electrical conductivity (EC) is prove...
ABSTRACT Free Space Optics communications (FSO) has drawn a bunch of attention for a range of applications in telecommunications field. The unregulated bandwidth which is up to 200THz, security, higher speed, unlimited data rate, low deployment cost, and shortest installation time frame are the few reasons to employ FSO system. However, weather attenuation has a massive impact on the FSO transmission channel. In this study, the effect of scintillation on the performance and FSO link availabil...
ABSTRACT Communication is the basis of all human interactions in the world. Thus, human beings have been struggling for years to introduce different communication transmission technologies. Lately, the two technologies namely Broadband over Power Line (BPL) and 4 th Generation/Long Term Evolution (4G/LTE) have been trending topics. Many researchers have been researching these technologies from different angles to make them better for use. There is a co-existence between BPL and LTE technolog...
