There are now more mobile phones (cell phones, smart phones, Ipads, etc) in the world than fixed phones; the plain old telephone system (POTS) is being replaced by the still rapidly growing mobile-radio system (MOBS).
Users can now transmit and receive not just audio, but also video and data signals, which in turn has led to the creation of a large number of social networks (Facebook, YouTube, Twitter, LinkedIn, etc ).
Amazingly this huge complex system performs very well most of the time. One crucial reason is that the information transmitted and stored in the system is protected against mistakes by powerful error-correcting codes.
The talk will describe how these codes work, and will highlight their error-correcting power with a practical demonstration.
