Polar code is a recent forward error correction technique that characterized by its low encoding/decoding complexity and good performance. In this paper, complete image transmission system (transmitter receiver) proposed to improve the quality over different types of channels such as Gaussian, Rayleigh Rician channels. The based on encoding most significant quantized Discrete Cosine Transform (...

The transmission rate is an important indicator for characterizing a virus and estimating the risk of its outbreak in certain area, but it hard to measure. COVID-19, instance, has greatly affected world more than 3 years since early 2020, scholars have not yet found effective method obtain timely due fact that value COVID-19 constant dynamic, always changing over time places. Therefore, order e...
