摘要
The invention particularly relates to an improved apparatus and method using the down-link prior adaptive filtering techniques, TDD scheme using the characteristics to improve the performance of a downlink system by giving to the obtained information, and compensating the derived information about the channel and apply to the adaptive pre-filter the data transmitted on the uplink to the downlink data in advance in transmission The purpose is to allow as. This invention's purpose is to analyze the transmission circuit 310 and the antenna 331 to the uplink signal (341) for generating a plurality of transmission signals having a primary path to input a signal to be transmitted to estimate the channel information and a reception circuit 330 (340), the filter tap coefficients based on the channel information in the reception circuit 330 (340) for calculating a pre-filter tap coefficient estimator (M1B1, M1B2 factor) 320 and the pre- filter tap coefficient estimator 320 to compensate suitably adapted for transmitting a transmission signal from the transmission circuit 310, the down-link through the plurality of antennas using a filter tap coefficient calculated in the pre-filter (321) 322 It characterized in that the configuration comprises a.
