Convolutional codes represent a cornerstone in modern communications, offering a method for continuously encoding data streams to mitigate errors due to interference and noise. These codes operate by ...

Polar codes represent a seminal breakthrough in error-correcting coding, enabling communication systems to approach the theoretical capacity of a channel with low-complexity decoding methods. Their ...

QR codes–square, dot-matrix variants of the venerable UPC–are becoming an increasingly popular way to share information such as URLs, contact details, GPS coordinates, and calendar events. The idea is ...

Last time, we looked into using a logic analyzer to decode SPI signals of LCD displays, which can help us reuse LCD screens from proprietary systems, or port LCD driver code from one platform to ...
