FPGA Block Parallel DF-MPIC Detectors DS-CDMA Systems Frequency-Nonselective Channels
2009/9/4
Multistage parallel interference cancellation- (MPIC-) based detectors allow to mitigate multiple-access interference in direct-sequence code-division multiple-access (DS-CDMA) systems. They are consi...
A Novel Macro-Block Group Scheme of AVS Coding for Many-Core Processor
Macro-Block Group AVS Coding Many-Core Processor
2008/12/31
The slice-level parallelism is popular in parallel video coding. However, the quality loses greatly because the dependency between macro-blocks is broken, especially on many-core platforms. To address...
Super resolution technique was first proposed for enhancing the image resolution, and then it was expanded to video sequence for obtaining a higher resolution video from low resolution input. Recently...
