چکیده

This paper presents a common framework for subband doubletalk detectors. Within this framework a number of low-complexity subband doubletalk detectors are evaluated in comparison with a corresponding fullband detector. The evaluation is performed by using real-data offline calculations. The evaluation indicates that the subband approach significantly improves the performance.

Estimating the Number of Wideband Radio Sources

In this paper, a new approach for estimating the number of wideband sources is proposed which is based on RSS or ISM algorithms. Numerical results show that the MDL-based and EIT-based proposed algorithm havea much better detection performance than that in EGM and AIC cases for small differences between the incident angles of sources. In addition, for similar conditions, RSS algorithm offers hi...
