Cross-spectrum and coherence function estimation using time-delayed Thomson multitapers
An idea is presented where multitapers are extracted from a known cross-spectrum and applied for estimation of the coherence function. An important property of the extracted windo...

On efficient soft-input soft-output encoding of convolutional codes
We study efficient algorithms for soft-input soft-output (SISO) encoding of convolutional codes. While the BCJR algorithm has been suggested for SISO encoding, we show that a for...
