Recent advances in artificial intelligence (AI) and machine learning (ML) have transformed our ability to decode complex ...

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 ...

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 ...

Software built into the cameras on iPhones and Android phones make quick work of decoding QR codes. How do you do that on a laptop or desktop computer?

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 ...

Product bar codes were originally developed to help with inventory tracking and speed up checkout at grocery stores. The relative speed and ease of use of the bar code system, or Universal Product ...

Here’s the front-end circuit of the IR sniffer. The hardware will capture an IR code and retransmit it on demand. The schematic isn’t particularly complex. The IR receiver module is represented here ...

While efforts in Europe focused on Enigma, the outcome of the Pacific War hinged on intercepting and breaking Japanese naval ...
