Artificial bandwidth extension of spectral envelope with temporal clustering
We present a new wideband spectral envelope estimation framework for the artificial bandwidth extension problem. The proposed framework builds temporal clusters of the joint sub-...

Iterative FDE for asynchronous single-carrier multiuser systems
When the arrival timing difference exists in the uplink MUMIMO systems, the conventional MUD techniques, without timing control, failed under this circumstance. In this paper, we ...

Gain and phase autocalibration for uniform rectangular arrays
—To maintain the performance of direction-of-arrival (DOA) estimation, an accurate model of the array response is required. In a time-varying sensor environment, this is only pos...
