Error correcting codes (ECC) for communications and storage

Aquí la idea es dar un panorama de redes del modelo de capas para identificar donde se encuentra ECC, después dar la perspectiva de sistemas de comunicaciones mostrando que al utilizar ECC se incrementa desempeño, después se platicaría de las técnicas de codificación desde códigos de bloques hasta llegar a turbo códigos. Se hablaría de las medidas de eficiencia de los códigos y los límites fundamentales como la capacidad de Shannon. Aquí es cuando lo podemos relacionar a 5G y otras tecnologías. En particular en tubo códigos podemos tratar con otros tipos de codificadores, como LDPC y mezclas para ver cómo se incrementa el desempeño.

Actualmente nosotros tenemos un laboratorio que le llamamos (no es oficial) Embedded Security. Lo trabajamos con una empresa en San Jose, California (Sage, Microelectronics) y con una universidad en China. Por este vínculo es que se orienta el trabajo hacia la parte de almacenamiento y utilizamos la perspectiva de turbo códigos con LDPC y BCH como codificadores principales. La diferencia es que en la primera parte con la perspectiva de sistemas de comunicaciones, los canales de comunicaciones son diferentes a la perspectiva de almacenamiento donde los canales se relacionan al proceso de lectura y escritura de chips de memorias Flash, por lo que los problemas deben ser tratados con otros modelos.

Biography:

Cesar received the Ph.D. and M.Sc. degrees in Electrical Engineering with major in Communications and Signal Processing, and a minor in Math from the Department of Electrical and Computer Engineering at Louisiana State University, Baton Rouge, LA, USA in 1996 and 1992, respectively. His Bachelors degree is in Mechanical and Electrical Engineering from UNAM in 1988. Dr. Vargas-Rosales is a member of the Mexican National Researchers System (SNI level II), the Academy of Engineering of Mexico (AIM) and the Mexican Academy of Sciences (AMC). He is a DIstinguished Lecturer of the IEEE Communications Society. He has been the IEEE Communications Society Monterrey Chapter Chair and the Faculty Advisor of the IEEE-HKN Lambda-Rho Chapter. He has also been the Technical Program Chair of the IEEE WCNC. He is currently the Leader of the Strategic Research Group on Telecommunications. He has co-authored several books one of them the book Position Location Techniques and Applications (Academic Press/Elsevier, 2009). His research interests are personal communications, 5G, cognitive radio, MIMO systems, stochastic modeling, intrusion/anomaly detection in networks, position location, interference, error correcting codes and reconfigurable networks. César Vargas Rosales specialized in communications and signal processing, a discipline based on mathematics and stochastic processes that allow its application on different areas such as radars, tracking, communications networks, propagation analysis, and sound system design, among others. The versatility of signal processing fascinates him, especially since knowledge evolves and this specialty is the foundation of other current studies: machine learning, deep learning, Bayesian decision theory, big data, data analytics, and neural networks. His studies enable his movement within research lines among communications. For instance, he can analyze cyber attacks by using signal processing and information theory tools, develop localization algorithms for sensor networks or drones through geometry, or apply Maxwell's equations to study signal propagation on different frequency bands.
