Performance Evaluation of QAM-Based BICM: An Analytical Approach
We present an analytical approach to determine the performance of bit-interleaved coded modulation (BICM) transmission over unfaded Gaussian channels. In particular, we derive expr...

The orientation adaptive lapped biorthogonal transform for efficient image coding
A lapped biorthogonal transform adapted for local directionality of an image is proposed. The proposed transform consists of overlapping basis functions and non-overlapping basis ...
