Joint speaker localization and array calibration using expectation-maximization

EURASIP Journal on Audio, Speech, and Music Processing

Table 5 Measures for various frequency offsets between arrays

Frequency offset ppm	Calib. SR (%)	MD(%)	FA (%)	Loc. RMSE [m]
0	100	0	0	0.117
100	100	0	0	0.117
250	100	33	0	0.118
1000	100	33	0	0.314
10000	0	100	83	-

The node calibration SR is measured in percentage (%). The source localization performance measures are MD percentage, FAs percentage, and RMSE in meters
