Analysis and Design of Dirty Paper Coding by Transformation of Noise
— We design a coding scheme for Costa’s dirty paper coding (DPC) [6] using a channel and a shaping code. We show that by transforming the channel noise distribution the DPC cha...

Efficient transform coding of two-channel audio signals by means of complex-valued stereo prediction
Traditional MDCT-based perceptual audio coding schemes employ mid/side and intensity stereo techniques to allow efficient joint coding of the two channels of a stereophonic signal...

Rate-distortion optimized transform for intra-frame coding
In this paper, a novel algorithm is proposed for intra-frame coding, named as rate-distortion optimized transform (RDOT). Unlike existing intra-frame coding schemes where the tran...

Video coding using Variable Block-Size Spatially Varying Transforms
In our previous work, we introduced Spatially Varying Transforms (SVT) for video coding, where the location of the transform block within the macroblock is not fixed but varying. ...

A Systematic Luby Transform Coded V-BLAST System
— Systematic Luby Transform (SLT) codes have shown good performance for single antenna aided systems for transmission over AWGN and uncorrelated Rayleigh fading channels. For the...
