Title:
METHOD FOR ASSIGNING TRANSMISSION CHANNEL AND RADIO UNIT ADOPTING THE METHOD
Document Type and Number:
Japanese Patent JP3229864
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for assigning a transmission channel that can connect a new user to a channel to which a base station can makes path multiple address providing less interference.
SOLUTION: A transmission reception system 1000 uses adaptive arrays 1010.1-1010.M to multiply a received weight vector to radio wave signals received by antennas #1-#4 respectively to separate signals from each user. A channel assignment device 1050 assigns transmission channels on the basis of a cross correlation of reception signal coefficient vectors of users having already been connected and new users calculated by a reception signal coefficient vector computer 1020 and of a reception signal power calculated by a reception signal power computer 1030.
