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 propotional to the frequency offset between the interfering sub-carriers and the victim sub-carriers.

摘要： The invention relates to a space-time-frequency encoding for use in wireless communication systems. According to the encoding scheme provided by the invention, it first transforms a plurality of input element pairs into a plurality orthogonal element pairs respectively, each of the plurality of input element pairs and corresponding orthogonal element pair forming an orthogonal matrix; and then maps the first element, second element and the redundancy of the second element in each of the plurality of input element pairs and corresponding orthogonal element pair as channel elements to three predetermined time-frequency cells in a first and second two-dimension time-frequency matrix so as to make the channel elements in the first and second matrixes suitable for being transmitted via different antennas. As the redundant input element pairs and corresponding orthogonal element pairs transmitted via different antenna are orthogonal in both space-time domain and space-frequency domain at the same time, and thus two-dimension space-time transmit diversity gain and space-frequency transmit diversity gain can be achieved at the same time.

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： The invention provides a multi-antenna transmission method. In this method, transmit antenna selection is performed for a portion of symbols to be transmitted based on channel state information from the transmit antennas to the receive antennas and a detection method used by the receiver, to select transmit antennas suitable for the portion of symbols, so that the transmitted symbols may have the lowest detection BER (Bit Error Rate). Based on the above idea, the invention proposes a PSM-HARQ method and apparatus based on transmit antenna selection, and it also proposes a method and apparatus for performing transmit antenna selection on spatial multiplexing signals in HSS-MIMO systems based on the post-detection SNR.

摘要： The invention relates to system synchronization in an orthogonal frequency division multiplexing communication system having a plurality of sub-carriers. The transmission signal provided by the invention comprises a plurality of frequency-domain symbols. Each frequency-domain symbol comprises both pilot elements and data elements that are modulated on different sub-carriers. The pilot elements in the plurality of symbols compose at least two pilot matrixes that have predefined relationship in frequency domain. At transmitting side, the plurality of symbols is transformed from frequency domain to time domain via Inverse Discrete Fourier Transform. At receiving side, the sampled time- domain symbols are transformed to frequency-domain symbols via Discrete Fourier Transform and at least two pilot matrixes having predefined relationship in frequency domain are retrieved based on pilot elements extracted from the plurality of frequency- domain symbols. Then the system synchronization can be obtained based on correlation of any two of the pilot matrixes. As the pilot timeslot carries pilot information and data information, the invention can improve transmission efficiency.
