Nonstationary multiple-antenna interference cancellation for unsynchronized OFDM systems with distributed training
Adaptive interference cancellation is addressed in an orthogonal frequency division multiplexing (OFDM) system with a frame containing a number of temporally distributed pilot sym...

A factor graph approach to joint iterative data detection and channel estimation in pilot-assisted IDMA transmissions
We consider a pilot-assisted interleave-division multiple access (IDMA) system transmitting over block-fading channels. We describe this system in terms of a factor graph and use ...

Minimum mean bayes risk error quantization of prior probabilities
Bayesian hypothesis testing is investigated when the prior probabilities of the hypotheses, taken as a random vector, must be quantized. Nearest neighbor and centroid conditions f...

Fast perfect weighted resampling
We describe an algorithm for perfect weighted-random sampling of a population with time complexity O(m + n) for sampling m inputs to produce n outputs. This algorithm is an increm...

A generalized optimal correlating transform for multiple description coding and its theoretical analysis
This paper considers a coding scheme for data transmission over erasure channels which is also known as multiple description coding. The LMMSE prefilter method of Romano [1] is r...
