Title:
ARRAY ANTENNA COMMUNICATION EQUIPMENT
Document Type and Number:
Japanese Patent JP3930456
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enhance the simplicity of a circuit configuration in array antenna communication equipment.
SOLUTION: Signals outputted from non-share circuit sections 24 are multiplied by code signals mutually orthogonally crossed with the signals for each unit antenna 12 by means of multipliers 102. Then, addition and composition are applied to the multiplied signals for input to a reception section (RX) 106. The output of the reception section (RX) 106 is multiplied by a code corresponding to each unit antenna 12 to regenerate a signal corresponding to each unit antenna 12. Each of the regenerated signals is inputted to an adaptive processing section 30. The circuit configuration is simplified by a portion of sharing the reception section (RX) 106 and an error in a delay amount between each of the signals is easily reduced. Consequently, control accuracy is more easily improved.
