Filed: 1992-07-21
Abstract: PURPOSE:To automatically correct positions of all satellites by rotating one parabolic antenna to store positions of plural satellites and setting the position of one satellite as the reference in the case of deviation of the parabolic antenna from a mast. CONSTITUTION:The reference position (east limit) of the rotation angle of a parabolic antenna 1 is stored in a storage part 7. An actuator 11 is driven from the reference position to direct the parabolic antenna to the first satellite. When the parabolic antenna 1 is rotated, pulses whose number corresponds to the rotation angle are generated from a pulse generating part 10. The number of pulses and the name of the set satellite are stored in the storage part 7. The actuator 11 is driven to direct the parabolic antenna 1 to the next satellite, and the position of this satellite is set in the same manner. Positions of all satellites are set in the same manner. If the parabolic antenna 1 is deviated, the actuator 11 is driven by the operation from an input part 16 to direct the parabolic antenna 1 again so that the radio wave from the first satellite can be received with the maximum sensitivity, thereby correcting the positions of all satellites.

Abstract: PURPOSE:To realize a highly efficient voice encoding method taking into account of information allocation in time axis by obtaining average amplitudes equivalent to plural frames for every band, referring to the learned code book and by deciding the amount of information to be allocated to each band and frame. CONSTITUTION:When average amplitudes equivalent to ten frames are stored in a memory, an adaptable bit allocation work starts. First, the vector whose elements consisting 4X10 average amplitude values is normalized (step 5). And a vector quantization takes place by selecting the code, which is nearest to the normalized average amplitude vector, from a code book (step 6). Then, from the selected code, the bit number is given which is allocated to the frame of each time of each bandwidth (step 7). And ADPCM coding is performed for each band (step 8). Here, ADPCM coded output is outputted in accordance with the allocated bit number. Lastly, code information, which indicates a bit allocation, and ADPCM coded output are multiplexed and outputted (step 9).
