Frame structure for filter bank multi-carrier (fbmc) waveforms
A unified frame structure for filter bank multi-carrier (fbmc) and orthogonal frequency division multiplexed (ofdm) waveforms may allow fbmc and ofdm frames to be communicated over a common channel without significant inter-frame gaps. The unified frame structure may set an fbmc frame duration to an integer multiple of an ofdm frame element duration to enable alignment of fbmc frames and ofdm frames in the time domain.

Rotary electrical machine control device
Regenerated power fed from a rotary electric machine is immediately reduced where connection between an electric machine and a dc power source is blocked. An inverter control section controls the inverter by controlling an armature current in a two-axis orthogonal coordinate system that rotates in synchronization with the rotary electric machine, the armature current being a vector obtained by synthesizing a field current and a drive current extending along respective axes of the orthogonal coordinate system.
