Single-channel hands-free teleconferencing systems are becoming popular. In order to enhance the communication quality of these systems, more and more stereophonic sound devices with two loudspeakers and two microphones are deployed. Because of the coupling between loudspeakers and microphones, there may be strong echoes, which make real-time communication very difficult. The best way we know to cancel these echoes is via a stereo acoustic echo canceller (SAEC), which can be modelled as a two-input/two-output system with real random variables. In this work, the authors recast this problem into a single-input/single-output system with complex random variables thanks to the widely linear model. From this new convenient formulation, thay re-derive the most important aspects of a SAEC, including identification of the echo paths with adaptive filters, double-talk detection, and suppression.


Image-guided Hypofractionated Stereotactic Radiosurgery

This book offers an up-to-date, practical guide to hypofractionated SRT for brain and spine metastases, as well as other tumor types such as glioma and benign tumors. The recent development of hypofractionated SRT, which calls for 1 to 5 fractions of high dose radiation to be delivered using special equipment, has resulted in the need for education on practice guidelines. This how-to guide emphasizes the pros and cons of hypofractionated SRT compared to single fraction radiosurgery.
