TRANSMISSION APPARATUS, RECEPTION APPARATUS, TRANSMISSION METHOD, AND RECEPTION METHOD

摘要

A transmission apparatus, reception apparatus, transmission method, and reception method are disclosed. The transmission apparatus includes: a modulation unit for modulating the signal to be transmitted by constellation, an encoding unit for grouping and double polarized space frequency or space time block encoding the symbols of the modulated signal, and the sign of the elements of the odd rows is opposite to the sign of the elements of the even rows in the block which is implemented double polarized space frequency or space time block encoding, and the elements of the first row and the elements of the third row constitute the code block of space frequency or space time block encoding, a frequency to time converting unit for implementing mapping from time to frequency and frequency to time conversion to the signal which is double polarized space frequency or space time block encoded, and transmitting the converted signal by corresponding antenna. The complexity of the scheme in the embodiment of the invention is lower, the scheme can apply to the actual communication system. And the additional spatial diversity gain can be provided; the robustness of the radio link's application in the high mobility is enhanced further.
