On-Channel Repeater And On-Channel Repeating Method

摘要

1. Technical Field of the invention set forth in the claims. ; Shall on-channel repeater and method thereof. ; 2. The invention is to solve the technical challenges. ; By removing the feedback signals generated due to low isolation of the transmitting and receiving antennas increases the channel repeater transmission output. ; 3. The gist of the solution of the invention. ; The reception channel on the basis of the subtraction means a signal subtraction by the subtraction means for subtracting a replica of the feedback signal from the receiving means the signal received by the receiving means receives the RF signal to convert the signal of the baseband reverse (inverse) using the filter tap coefficient of the filter tap coefficients generated inverse channel estimation means by the reverse channel estimation means for generating an estimate first adaptive filtering means to the second to compensate for the channel of the subtracted signal distortion by the subtraction means converting the channel distortion-compensated signal by the first adaptive filtering means to the RF signal by a transmitting means down-converting means and said down-converting means for down-converting the RF signal converted by the transmission means in the baseband to a wireless transmission by calculating the replica on the basis of the signal subtracted by the converted baseband signal and said subtraction means including a replica generation means for feedback to said subtraction means. ; 4. important use of the invention ; Yiyongdoem on-channel repeater. ; The same channel, relay, feedback signal
