Cramer-Rao lower bound on doppler frequency of coherent pulse trains
This paper derives the Cramer-Rao lower bound (CRLB) on estimates of the frequency of a coherent pulse-train passively intercepted at a moving antenna. Such estimates are used to ...

Estimating the dominant person in multi-party conversations using speaker diarization strategies
In this paper, we apply speaker diarization strategies from a single source to the task of estimating the dominant person in a group meeting. Previous work has shown that speaking...

Structure of non-binary regular ldpc cycle codes
In this paper, we study non-binary regular LDPC cycle codes whose parity check matrix has fixed column weight 2 and fixed row weight d. We prove that the parity check matrix of ...
