摘要： The present invention provides a transmission method and apparatus for cancelling inter-carrier interference in wireless communication systems. Particular carriers are not used for data transmission but carry weighted data to cancel the ici interference of a first group of interfering sub-carriers onto a second group of victim sub-carriers. The weights are inversely proportional to the frequency offset between the interfering sub-carriers and the victim sub-carriers.

摘要： The present invention provides a space-time-frequency encoding and decoding method and apparatus used in a wireless communication system. With the encoding method provided in the invention, transmission code words and their redundant elements are properly allocated on space-time-frequency units, so that the transmission codes and their partial redundancies can be transmitted via different antennas. Accordingly, at the receiving side, the redundant elements and the corresponding code word elements can be combined, so as to enhance the SNR and diversity gains for a part of the elements in the code words, and hence enhance the reception quality for the overall data stream.

摘要： A space-time-frequency encoding scheme, for use in wireless communication systems, transforms a plurality of input element pairs into a plurality orthogonal element pairs, each of the plurality of input element pairs and corresponding orthogonal element pairs forming an orthogonal matrix. A first element, second element and a duplicate of the second element in each of the plurality of input element pairs and corresponding orthogonal element pairs are mapped as channel elements to three predetermined time-frequency cells in respective first and second two-dimension time-frequency matrixes for transmission via different antennas. As the input element pairs and corresponding orthogonal element pairs, transmitted via different antennas, are orthogonal in both the space-time domain and the space-frequency domain at the same time, two-dimension space-time transmit diversity gain and space-frequency transmit diversity gain can be achieved at the same time.
