Research Interests
|
|
Research topics include information theory and coding, communication theory, and digital signal processing. I am particularly interested in error correcting codes for reliable communications, intersymbol-interference channels, digital watermarking and signal processing for magnetic recording. Of current interested are high-dimension lattices for communications, design and implementation of low-density parity-check codes, and turbo equalization.
