Adaptive Bit Rate Control in Semantic Communication With Incremental Knowledge-Based HARQ

Incremental adaptive networks implemented by free space optical (FSO) communication

The aim of this paper is to fully analyze the effects of free space optical (FSO) communication links on the estimation performance of the adaptive incremental networks. The FSO links in this paper are described with two turbulence models namely the Log-normal and Gamma-Gamma distributions. In order to investigate the impact of these models we produced the link coefficients using these distribu...

Least Bit Error Rate Adaptive

Implementation Experiment of Vtp Based Adaptive Video Bit-rate Control over Wireless Ad-hoc Network

In wireless ad-hoc network, knowing the available bandwidth of the time varying channel is imperative for live video streaming applications. This is because the available bandwidth is varying all the time and strictly limited against the large data size of video streaming. Additionally, adapting the encoding rate to the suitable bit-rate for the network, where an overlarge encoding rate induces...

Intelligent Communication for Low Bit Rate Channels

In this paper, intelligent compression techniques to allow transmission of text and image data over low bit rate channels are proposed. For text, a compression technique for English language text is presented. Compression is carried out by deleting characters that are not necessary for comprehension by a human reader. Decompression is carried out on a sentence by sentence basis using a database...

Adaptive Minimum Bit-Error-Rate Filtering

Adaptive filtering has traditionally been developed based on the minimum mean square error (MMSE) principle and has found ever-increasing applications in communications. The paper develops adaptive filtering based on an alternative minimum bit error rate (MBER) criterion for communication applications. It is shown that the MBER filtering exploits the non-Gaussian distribution of filter output e...
