摘要： In a single-carrier frequency division multiple access (SC-FDMA) system that utilizes interleaved FDMA (IFDMA) or localized FDMA (LFDMA), a transmitter generates modulation symbols for different types of data (e.g., traffic data, signaling, and pilot) and performs code division multiplexing (CDM) on at least one data type. For example, the transmitter may apply CDM on signaling and/or pilot sent on frequency subbands and symbol periods that are also used by at least one other transmitter. To apply CDM to a given data type (e.g., signaling), the transmitter performs spreading on the modulation symbols for that data type with an assigned spreading code. CDM may be applied across symbols, samples, samples and symbols, frequency subbands, and so on. The transmitter may perform scrambling after the spreading. The transmitter generates SC-FDMA symbols of the same or different symbol durations for traffic data, signaling, and pilot and transmits the SC-FDMA symbols.

摘要： The present invention discloses a method for suppressing cross-slot interference in a time-slotted CDMA system. The method includes: determining, by a base station, positions of cross slots according to configuration information of local cell and configuration information of co-frequency adjacent cells, and performing multi-cell channel estimation on the cross slots to obtain channel estimation results; determining, by the base station, code channel configuration information of the co-frequency adjacent cells, grouping the determined code channels and determining the code channels of the co-frequency adjacent cells involved in a joint detection; and performing, by the base station, the joint detection according to the multi-cell information estimation results and the determined code channels of the base stations involved in the joint detection to obtain detection data. With the present invention, interference from a base station transmitting downlink signals in cross slots to a base station receiving uplink signals in the corresponding slot may be reduced, and the system capacity and the stability may be improved.

摘要： PROBLEM TO BE SOLVED: To simplify a user equipment of multiple access communication using a shared frequency spectrum such as a TDD/CDMA communication system. SOLUTION: A transmitter site transmits a plurality of data signals over a shared frequency spectrum in a code division multiple access (CDMA) communication system. Each transmitted data signal experiences a similar channel response. A receiver side receives a combined signal of the transmitted data signals. The combined signal is sampled at a multiple of the chip rate. The channel response for the combined signal is determined. A first element of a spread data vector is determined using the combined signal samples and the estimated channel response. Using a factor from the first element determination, remaining elements of the spread data vector are determined. The data of the data signals are determined using the determined elements of the spread data vector. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To reduce complexity in detecting data at high speed. SOLUTION: K data signals are transmitted over a shared spectrum. A composite signal is received and sampled over the shared spectrum (48). The composite signal has the K transmitted data signals (48). A composite channel response matrix is generated (49) using a code and an impulse response of the K transmitted data signals. A block column of a composite channel correlation matrix is determined using the composite channel response matrix (50). Each block entry of the block column is a K by K matrix (51). At each frequency point k, the K by K matrix is determined by taking the Fourier transform of the block entries of the block column (52). An inverse of the K by K matrix is multiplied to the result of the Fourier transform (52). Data are retrieved from the K data signals using an inverse Fourier transform (55).
