摘要
The present invention was directed to a downlink improved apparatus and method with pre-adaptive filtering techniques, especially, adapt the data transmitted over the uplink using the characteristics of the TDD scheme applied to the pre-filter deriving information about the channel and the derivation to compensate for the information to the data in advance when there is a downlink transmission by giving as the purpose to improve performance of the DL system. The present invention for this purpose is the estimated channel information by analyzing the signal which is an uplink from a transmission circuit 310, and a plurality of antennas 331, 341 for generating a plurality of signals having a path difference the signal to be transmitted to the input and a receiving circuit 330, 340 and the reception circuit 330 based on the channel information on the 340 filter tap coefficients pre-filter tap coefficient estimator 320 to calculate (M1B1, M1B2 coefficient), the using the filter tap coefficient calculated in the pre-filter tap coefficient estimator 320, by having an adaptive prefilter 321, 322 to properly compensate for a transmission signal in the transmitting circuit 310, a DL that the configuration It characterized.
