<p>An information transmission method, an information reception method and devices thereof are disclosed in the invention. The information transmission device includes a coding module and at least two modulation transmission modules. The coding module is used to perform combination coding of space-frequency block code and frequency switched transmission diversity on a symbol stream, and transmit the four paths of code streams generated through the coding into two adjacent base stations respectively, the two antennas of each base station obtain two paths of code streams in the four paths of code streams, wherein the two paths of code streams obtained by the two antennas of each base station include all modulated symbols in the symbol stream. The modulation transmission module is used to map the symbols in each code stream to the Orthogonal Frequency Division Multiplexing (OFDM) sub-carriers of the corresponding antenna to perform OFDM modulation and transmission. By transmitting the coded code streams into the base stations of two adjacent cells to perform distributed transmission, the problem of interference between adjacent cells is solved effectively.</p> |
