In view of the diverse jamming environment, single-level anti-jamming method faces some challenges such as poor timeliness, high cost and effect. this paper, routing delay, overhead diversified threats are comprehensively considered. addition, a cross-layer is proposed in scenario busy satellite Internet communication. The involves two levels: link-layer based on path repair network-layer recon...

The paper discusses various system aspects of future aeronautical services via satellite. Both, commercial aeronautical broadband satellite communications (AirCom) for passengers and air traffic management (ATM) are considered. An integrated global system design approach is presented, and key R&D issues along this path are discussed. Some focus is laid on geographic satellite coverage and const...

Nowadays a lot of satellite images are being received every day from several satellite sensors and with different resolutions. These images, especially Very High Resolution (VHR) satellite imagery (such as Ikonosand and Quickbird) provide valuable information to researchers for different applications. Because amount of remotely sensed data is enormous, for a human expert, manually extracting th...

current study basically aims at exploring the motives behind watching persian satellite channels among female audience in city of qaemshahr. participants are 263 female audiences from qaemshahr which were selected based on purposive sampling. the research method employed here is survey, and a researcher-developed questionnaire was used to collect data, one-sample t-test, anova, and friedman tes...

in this paper, an interference management for multi-beam satellite network to enhance spectral efficiency is studied. first, a two-satellite for future generation satellite network using cognitive radio technology is provided.this network is composed of a secondary satellite and aprimary satellite where the primary satellite system does not suffer from severe destructive interferences coming fr...

––Satellite image compression is one of active image processing areas. In this paper we proposed a novel approach for ROI compression of multiband satellite images using modified JPEG standard. In this paper, we show how the quantization may be adapted in each block and how we may signal to the decoder in a memory-efficient manner. This allows ROI coding of satellite images. The method takes ad...
