2019 2019 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)  
Abstract-Halftone based block truncation coding images (H-BTC) are the improved version of BTC images which can offer superior representation and enhanced image quality.  ...  The developed H-BTC database comprises of 30K images comprising of the five types of H-BTC images in which three categories are constructed based on digital halftoning and two types are based on digital  ...  G polar T inner H T ldpc = 0 (1) In order to decode the received sequence using BP decoding of LDPC code, the condition of (1) must be satisfied. Consider the polar code of R = 1/2.  ...

Implementation of Fog computing for reliable E-health applications

Razvan Craciunescu, Albena Mihovska, Mihail Mihaylov, Sofoklis Kyriazakos, Ramjee Prasad, Simona Halunga
2015 2015 49th Asilomar Conference on Signals, Systems and Computers  
Specifically, we introduce a concept for sparse joint activity, channel and data detection in the context of the Coded ALOHA (FDMA) protocol.  ...  In addition, we will improve on the performance of such Coded ALOHA protocols in terms of the resource efficiency.  ...  (LDPC) decoders.  ...

Ping-pong beam training for reciprocal channels with delay spread

Elisabeth de Carvalho, Jorgen Bach Andersen
2015 2015 49th Asilomar Conference on Signals, Systems and Computers  
Specifically, we introduce a concept for sparse joint activity, channel and data detection in the context of the Coded ALOHA (FDMA) protocol.  ...  An important aspect is robust and resource efficient preamble design to minimize missed detection and false alarm probabilities of service requests.  ...  LDPC) decoders.  ...
