Method for constructing space-time/space-frequency code, and transmitting method and apparatus

A transmitting method based on a space-time/space-frequency code, comprising:

• obtaining information symbols to be transmitted;
• and
• transmitting the information symbols according to a space-time/space-frequency code matrix;
• wherein the space-time/space-frequency code matrix is capable of being divided into at least two sub matrixes, the at least two sub matrixes comprises:
• at least two Toeplitz matrixes, or comprises Toeplitz matrixes and at least one zero matrix, the Toeplitz matrixes are corresponding to nonzero elements in a given Orthogonal Space-Time Block Coding (OSTBC) matrix respectively, and when the OSTBC matrix comprises a zero element, the zero matrix is corresponding to the zero element in the OSTBC matrix.

A transmitting apparatus, comprising:

• an obtaining module, configured to obtain information symbols to be transmitted;
• and
• a transmitting module, configured to transmit, according to a space-time/space-frequency code matrix, the information symbols that are to be transmitted and are obtained by the obtaining module, wherein the space-time/space-frequency code matrix is capable of being divided into at least two sub matrixes, the at least two sub matrixes comprises:
• at least two Toeplitz matrixes, or comprises Toeplitz matrixes and at least one zero matrix, the Toeplitz matrixes are corresponding to nonzero elements in a given Orthogonal Space-Time Block Coding (OSTBC) matrix respectively, and when the OSTBC matrix comprises a zero element, the zero matrix is corresponding to the zero element in the OSTBC matrix.
