Transmission performance in compressed medical images using turbo code

Abstract

Medical imaging is now an essential support for screening, diagnosis, treatment protocols implementation, patient monitoring, operative preparation and post-operative control. In addition, scientific and technological advances make it possible to set up new imaging methods, often complementary to the existing ones, but also to gradually improve their accuracy. The result is an increase, in the acquisitions number made for the same patient and for information produced for each examination. Since these images must be kept for a certain period, the storage space required for archiving all this data is constantly evolving and images are often viewed locally, and it can be viewed remotely through networks with limited bandwidth such as the long term evolution (LTE) mobile network. The use of compression quickly proves to be essential, whether to facilitate storage or for these data mass browsing remotely. The results of the work carried out in this article are mainly focused on the medical images compression by the set partitioning hierarchical trees (SPIHT) method, which, in fact, allow a significant reduction for data. We are also interested in the transmission of these images on an LTE mobile radio channel in a way that can provide a high bitrate with good transmission quality, by exploiting the channel coding technique, which is effective in combating the noise introduced during the transmission of these images.

A deep dive into enhancing frequency stability in integrated photovoltaic power grids

“…This study aims to explore the advantages of frequency stability analysis in the context of PV integration. By understanding the factors influencing frequency variations and implementing control measures, PV system integration can be enhanced, performance optimized, and grid disruptions reduced [39]- [41]. Figure 3 illustrates daily load profiles on active and reactive power (PQ) buses, depicting typical electricity demand patterns with peak hours and lower demand periods, which may vary daily, particularly during morning and evening peaks when residential and commercial activities are most active.…”

Application of iterative decoding systems (UTTCM) to 4G-LTE mobile radio communication network

“…As we can reduce the complexity of decoding while maintaining the same performance of this code as described in [4,5,6]. As a result, the practical advantage of localized iterative decoding is that powerful codes can now be decoded with reasonable complexity [7], which is why much of the research is focused on evaluating the performance of iterative decoding for the future of LTE network systems [8]. Proakis considered in [9] that The turbo-code is an evolution of convolutive coding technology used in all previous standards with impressive performance in terms of capacity in nearby channels.…”
