4. 3. Implementation and optimization of LDPC decoding algorithms tailored for Nvidia GPUs in 5G

   University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013); Karlstads universitet/Avdelningen för datavetenskap

   Author : Benjamin Salomonsson; [2022]
   Keywords : New Radio NR ; Shared Channel; Channel Coding; Low Density Parity-Check LDPC ; Min-Sum Algorithm MSA ; Graphics Processing Unit GPU ; Compute Unified Device Architecture CUDA ;

   Abstract : Low-Density Parity-Check (LDPC) codes are linear error-correcting codes used to establish reliable communication between units on a noisy transmission channel in mobile telecommunications. LDPC algorithms detect and recover altered or corrupted message bits using sparse parity-check matrices in order to decipher messages correctly. READ MORE
