    Abstract: A linear space-time code generating method for FDFR(Full Diversity and Full Rate), and a multi-antenna system using the space-time code are provided to cope with a channel change effectively and have a minimum complexity in using a maximum induction detector because a space-time codeword has a minimum number of data symbols. When data is inputted to a space-time coder, the space-time coder sets columns and rows of a codeword matrix for determining a space-time code(102). The number of symbols to be transmitted during a single block interval is determined by the product of the number of antennas of a transmitter and a space multiplexing rate(104). A particular column of the codeword matrix is selected and the number of symbols corresponding to the number of antennas is allocated to rows corresponding to the number of the space multiplexing rate in the selected column(106). A complex weight value corresponding to the allocated symbols is allocated to each symbol so as for each symbol to be combined with the complex weight value(108). Different symbols are allocated to each row and each column of the codeword matrix, and each different complex weight value is allocated to the same symbols allocated to each column(110).

A transmitting unit in a multi-carrier based mobile communication system comprises a pilot creation module(200), a spread spectrum module(100), an IDFT(Inverse Discrete Fourier Transform) module(300), and a parallel-serial conversion module(400).

The spread spectrum module(100) creates received serial data into parallel data, performs spectrum spreading for the created data, and adds the grouped pilot to them. The IDFT module(300) executes IDFT for the data received from the spread spectrum module(100). The parallel-serial conversion module(400) converts the IDFT-processed data into serial data.
