Self-correcting quantum memories demonstrate robust properties that can be exploited to improve active error-correction protocols. Here we propose a cellular automaton decoder for variation of the color code where bases physical qubits are locally rotated, which call XYZ code. The local transformation means our demonstrates key two-dimensional fractal if noise acting on system is infinitely bia...

This paper investigates the unsourced random access (URA) scheme to accommodate numerous machine-type users communicating a base station equipped with multiple antennas. Existing works adopt slotted transmission strategy reduce system complexity; they operate under framework of coupled compressed sensing (CCS) which concatenates an outer tree code inner for slot-wise message stitching. We sugge...

A high-quality MPEG-2 software decoder should support a good scalability performance for a wide range of video format, especially for the high-resolution MPEG-2 video (e.g., HDTV). However, It is found that the existing parallel decoder suffers significant performance degradation when decoding high-level MPEG2 video with the full system configuration, due to inefficient management of memory spa...

We propose to use multiple-description coding (MDC) to protect video information against packet losses and delay, while also ensuring that it can be decoded using a standard decoder. Video data are encoded into a high-resolution stream using a standard compliant encoder. In addition, a low-resolution stream is generated by duplicating the relevant information (motion vectors, headers and some o...

This paper presents a high-throughput hardware design for the Switchable Loop Restoration Filter (SLRF) of AOM Video 1 (AV1) video format. includes two filters defined at AV1 SLRF: Separable Symmetric Normalized Wiener (SSNWF) and Dual Self- Guided (DSGF). The SLRF is last step in loop restoration filters, it used to attenuate blurring artifacts, improving subjective quality coding efficiency. ...
