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 (...

We propose two new classes of non-adaptive pooling designs. The first one is guaranteed to be -error-detecting and thus -error-correcting, where , a positive integer, is the maximum number of defectives (or positives). Hence, the number of errors which can be detected grows linearly with the number of positives. Also, this construction induces a construction of a binary code with minimum Hammin...

Computational devices are becoming ubiquitous. Nowadays, with devices such as cellular phones, we can access and manipulate information at anytime, stored anywhere. In this ubiquitous computing scenario, it is common to require from these systems the ability to adapt as a response to changes in their operating environment, being therefore adaptive. However, adaptability often increases the comp...
