Claim 1
Independent Claim
238 words
A phase adjusting system for a radio communication system comprising, a plurality of transmitters (11, 13, 15, 17), to each of which a target number is assigned for phase adjustment, a plurality of receivers (12, 14, 16), each receiving transmitting signal from a corresponding one of said plural transmitters, delay time setting circuits (26) in each of which the delay time of a corresponding one of the transmitters (11, 13, 15, 17) is set, means (25) for detecting the delay time of a target transmitter selected in accordance with its target number, and means (21) for controlling a corresponding one of the delay time setting circuits (26) and the said means (25) for detecting to calculate the delay time difference between the detected delay time and a reference delay time, and to set a delay time dependent on the delay time difference in the corresponding one of the delay time setting circuits, the target transmitter being thereby adjusted in phase, characterized by a memory (23) for storing the target numbers in sequential order of said target transmitter among said plural transmitters, an input/output terminal (22) for changing the content of memory, and wherein the said sequential order of the target numbers in the memory (23) is changed in accordance with the input of commands from the terminal (22) to the control means (21), whereby the phase adjusting order of the transmitters is changed without changing their target numbers.
Claim 2
Dependent Claim
238 words
A phase adjusting system for a radio communication system comprising, a plurality of transmitters (11, 13, 15, 17), to each of which a target number is assigned for phase adjustment, a plurality of receivers (12, 14, 16), each receiving transmitting signal from a corresponding one of said plural transmitters, delay time setting circuits (26) in each of which the delay time of a corresponding one of the transmitters (11, 13, 15, 17) is set, means (25) for detecting the delay time of a target transmitter selected in accordance with its target number, and means (21) for controlling a corresponding one of the delay time setting circuits (26) and the said means (25) for detecting to calculate the delay time difference between the detected delay time and a reference delay time, and to set a delay time dependent on the delay time difference in the corresponding one of the delay time setting circuits, the target transmitter being thereby adjusted in phase, characterized by a memory (23) for storing the target numbers in sequential order of said target transmitter among said plural transmitters, an input/output terminal (22) for changing the content of memory, and wherein the said sequential order of the target numbers in the memory (23) is changed in accordance with the input of commands from the terminal (22) to the control means (21), whereby the phase adjusting order of the transmitters is changed without changing their target numbers.
Claim 3
Dependent Claim
49 words
A phase adjusting system for a radio communication system according to claim 1, characterized in that a reference transmitter (e.g. No. 1) is selected in correspondence with the target transmitter (e.g. No. 2) from among the plurality of transmitters (11, 13, 15, 17) to provide the reference delay time.
Claim 4
Dependent Claim
30 words
A phase adjusting system for a radio communication system according to claim 2, characterized in that the memory (23) stores the relation of the reference transmitter to the target transmitter.
