Abstract: In this paper, a method for joint source-channel coding (JSCC) based on concatenated spatially coupled low-density parity-check (SC-LDPC) codes is investigated. A construction consisting of ...
Abstract: In this letter, an adaptive decoding algorithm with a variable sliding window for joint source-channel coding (JSCC) scheme based on double spatially coupled low-density parity-check ...
Even though many people don't yet have Wi-Fi 7 routers or client devices, a new wireless standard, Wi-Fi 8, is set to make its official debut sometime in 2028. Yes, that’s still nearly two years away, ...
The development of the 6G standard is entering a more concrete phase. At the June 2026 3GPP RAN Plenary in Singapore, the industry advanced several key areas under study and finalized the timeline for ...

LDPC codes, how small random parity sets unlocked reliable communication
Every transmission channel loses bits, and the real puzzle is how to recover them without slowing everything down. This video traces the elegant logic behind low-density parity-check codes, from ...
Anthropic’s AI coding agent silently encoded proxy hostnames and Chinese timezone data into invisible Unicode characters ...
Need more reliable wireless internet? Wi-Fi 8 promises trouble-free connections. Here’s everything you need to know about the tech behind it, plus when you can expect the first routers to hit the ...
self.alpha= tf.get_variable(name=self.alpha_name, shape=[1], dtype=tf.float32, initializer=tf.contrib.layers.xavier_initializer()) self.best_alpha = tf.Variable(tf ...
A Python implementation of an LDPC (Low-Density Parity-Check) Encoder and Decoder built from scratch using NumPy and Matplotlib, without any external LDPC libraries. The project demonstrates the ...
