    Abstract: A rotary electric machine includes a rotor, and a stator facing the rotor with a predetermined gap interposed between the rotor and stator. The stator has a stator core formed in a substantially circular annular shape and provided with an armature slot and a field slot alternately arranged in a circumferential direction, an armature winding housed in the armature slot, and a field winding and a first field magnet housed in the field slot. The armature winding generates a rotating magnetic field to rotate the rotor by being supplied with an alternating current armature current. The field winding generates a field flux by being supplied with a direct current field current. The first field magnet changes a magnetic force by the field flux.

    Abstract: A communication device is configured to correlate a first signal with a second signal at a designated interval, the second signal corresponding to the first signal and being received by the communication device where the other communication device transmits a signal including a pulse as the first signal, convert a correlation computation result that is a result of correlating the first signal with the second signal at the designated interval into a format including a matrix product of an expanded modal matrix and an expanded signal vector, the expanded modal matrix including a plurality of elements indicating the correlation computation result obtained when assuming that the signals are received at respective set times, the expanded signal vector being a vector including a plurality of elements, each of which indicates whether or not there is a signal received at each of the set times and amplitude and phase of the signal.
