摘要： A method and apparatus for generating an impulsive wave in an OFDM communication system where L subcarriers are allocated to reserved tone locations among N subcarriers and data is carried on (N-L) subcarriers (L is less than N). In the method, a predetermined number of random sets each having L tone locations are created. Subcarriers are allocated to the L tone locations of each of the random sets without overlapping and IFFT-processed. A secondary peak value of the IFFT signal is stored. Tone location information having a lower secondary peak value than the stored secondary peak value is detected by fixing (L-1) tone locations and substituting subcarriers other than the subcarriers at the (L-1) tone locations one by one for the remaining one tone location. The tone location information is stored.

摘要： A space-time block coding apparatus and method for transmitting an input symbol sequence through a plurality of Tx antennas using a channel information from the receiver in order to improve the performance of a space-time block coding (STFBC). A pre-coder pre-codes an input symbol sequence by multiplying the input symbol sequence by ejθ, θ being a phase rotation angle, the pre-coded symbol sequence being reconstructed to have real and imaginary parts. A grouping mapper forms a grouping pattern based on feedback channel information received from a receiver, and generates a grouping symbol sequence by multiplying the grouping pattern by the pre-coded symbol sequence. A mapper generates symbol vectors by recombining the real and imaginary parts of the grouping symbol sequence in an interleaving scheme. A plurality of Alamouti coders encodes the symbol vectors in an Alamouti scheme and transmits the encoded symbol vectors through corresponding transmit antennas.
