MIT figures out a way to improve cellular reception
So after taking a timeout from playing World of Warcraft, these MIT geniuses decided to use a long code name broken up into chunks. Professor Gregory Wornell, in the Department of Electrical Engineering and Computer Science at MIT, says "The transmission strategy is that we send the first part of the codeword. If it doesn't succeed, we send the second part, and so on. We don't repeat transmissions: We always send the next part rather than resending the same part again. Because when you marry the first part, which was too noisy to decode, with the second and any subsequent parts, they together constitute a new, good encoding of the message for a higher level of noise." In English, the system sends a codeword broken into sections. These sections are sent in sequence until enough of the code can be recognized and decrypted. This works regardless of the level of noise in the channel.
While still in a research phase, H. Vincent Poor, dean of the School of Engineering and Applied Science at Princeton University, says that commercial deployment is not too far away. Poor says, "The codes are inherently practical. In fact, the paper not only develops the theory and analysis of such codes but also provides specific examples of practical construction."
And if you start to feel that headache coming on, just be glad that you don't need to know exactly how you smartphone works inside to be able to enjoy of the features available on it.
