ECMA-407: New Approaches to 3D Audio Content Data Rate Reduction with RVC-CAL

Marco Mattavelli, Claudio Paolo Alberti, Junaid Jameel Ahmad

Inverse problems have only been known in spatial audio for a very short time; their only solution, called "inverse coding" in literature, is essentially based on time-level modeling. Inverse problems, however, unlike parametric coding, require only an init ...

Robust Non-Coherent Timing Acquisition in IEEE 802.15.4a IR-UWB Networks

Jean-Yves Le Boudec, Ruben Merz, Manuel Flury

Non-coherent energy-detection receivers are an attractive choice for IEEE 802.15.4a networks. They can exploit the ranging capabilities and the multipath resistance of impulse-radio ultra-wide band (IR-UWB) at a low complexity. However, IEEE 802.15.4a rece ...
