Abstract: A transmission apparatus for a DS/CDMA system including a multiple-input multiple output MIMO antenna system is disclosed. The apparatus includes a transmitter for transmitting data by applying a different scramble code to each transmitted data through a plurality of transmitting antennas. The apparatus also includes a receiver for receiving the transmitted data by obtaining a diversity gain based on the maximum order of the diversity in order to effectively detect the data. The present invention achieves an excellent detection performance by receiving data with a full order of diversity, which is a multiple of the number of receiving antennas and the number of multipath, without complicated operation such as a decision feed equalizer.

Abstract: PURPOSE: An adaptive interference mitigating receiver for a DS/CDMA communication system using space-time block coding is provided for a quality service at a high speed by improving data detection performance in a multi-path fading channel environment. CONSTITUTION: Chip matching filters(210,220) match-filter signals received from antennas(40) on the basis of a chip period and output them. Input signal generation buffers(310,320) generate vectors corresponding to signal blocks outputted from the chip matching filters(210,220) and output them according to a symbol period. Adaptive filter blocks(410-440) filter signals outputted from the input signal generation buffers(310,320) according to a tab weight controlled by a specific period and output them. A coupler(600) couples the signals outputted from the adaptive filter blocks(410-440) and outputs it. A data determining unit(700) restores an original signal that a specific user intends to transmit by using a signal outputted by the coupler(600). A reference signal selector(800) selectively outputs either a signal outputted from the data determining unit(700) or a learn data signal. Error generation blocks(510-540) generate an error signal for controlling a tap weight used in the adaptive filter blocks(410-440) by using a signal outputted from the reference signal selector(800) and a signal outputted from the adaptive filter blocks(410-440).
