Adaptive System Identification in the Short-Time Fourier Transform Domain Using Cross-Multiplicative Transfer Function Approxima
In this paper, we introduce cross-multiplicative transfer function (CMTF) approximation for modeling linear systems in the short-time Fourier transform (STFT) domain. We assume tha...

Tones for Real: Managing Multipath in Underwater Acoustic Wakeup
The principles of sensor networks--low-power, wireless, in-situ sensing with many inexpensive sensors--are only recently penetrating into underwater research. Acoustic communicati...

Multichannel noise reduction using low order RTF estimate
The relative transfer function generalized sidelobe canceler (RTF-GSC) is a popular method for implementing multichannel speech enhancement. However, an accurate estimation of cha...

Receiver Multiuser Diversity Aided Multi-Stage MMSE Multiuser Detection for DS-CDMA and SDMA Systems Employing I-Q Modulation
Abstract— The so-called receiver multiuser diversity aided multistage minimum mean-square error multiuser detector (RMD/MS-MMSE MUD), which was proposed previously by the author,...
