    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.

    摘要: An encoding apparatus and method in a communication/broadcasting system are provided. When an encoding symbol is generated using at least one source symbol from among total source symbols to be encoded, encoding symbols are generated by using each of the total source symbols with a uniform probability before repeatedly using any of the total source symbols.
