摘要： Reception level frequency distribution is determined. A frequency correlation bandwidth is determined in accordance with intervals between peaks or dips, or alternatively intervals between intersections wherein the reception level frequency distribution intersects a threshold. At the time of reception start, a training mode period is set up to determine a frequency correlation bandwidth. After the training mode period, signals are received in accordance with the determined frequency correlation bandwidth. The frequency correlation bandwidth is determined with increased precision to avoid a large amount of calculation such as Fourier transform. As a result, the entire diversity reception processing requires a reduced amount of calculation.

摘要： A process for producing a rare earth-iron-boron magnet, which includes the steps of: (1) charging a melt spun powder of a rare earth-iron-boron magnet into at least one cavity, which is confined by a pair of electrodes inserted into a hole of an electrically non-conductive ceramic die; (2) subjecting the melt spun powder to a non-equilibrium plasma treatment, under a reduced atmosphere of 10.sup.-1 to 10.sup.-3 Torr, while applying a uniaxial pressure of 200 to 500 kgf/cm.sup.2 to the melt spun powder in the direction connecting the electrodes interposed between a pair of thermally insulating members, thereby fusing the melt spun powder; and (3) heating the fused melt spun powder to a temperature higher than or equal to its crystallization temperature by transferring a Joule's heat generated in the thermally insulating members by passing a current through the members to the melt spun powder thereby causing the plastic deformation of the melt spun powder to form a rare earth-iron-boron magnet.
