Abstract: Detecting arm movement direction is significant for individuals with upper-limb motor disabilities to restore independent self-care abilities. It involves accurately decoding the fine ...

Abstract: We apply the innovations method to Viterbi decoding of convolutional codes. First, we calculate the covariance matrix of the innovation (i.e., the soft-decision input to the main decoder in ...

Encode and decode messages using sound waves. Support for multiple transmission protocols. Optional real-time audio transmission and reception via PyAudio. GGWave transmits data using frequency-shift ...

Across the ancient world, messages were carved into stone, clay, and earth — yet many remain undeciphered. These symbols outlasted the cultures that created them, leaving meaning behind. Without ...
