摘要： It is possible to provide a base station device, a mobile station device, a communication system, a channel estimation method, a transmission antenna detection method, and a program which can employ PVS as the SCH transmission diversity method and avoid a side lobe to improve the adjacent cell search performance. When employing the PVS on the frequency axis of the SCH in these, different precoding weights are applied between sub carrier groups so as to correlate a plurality of PSC sequences to a precoding weight matrix and identify the PSC sequence. Moreover, the number of sub carriers to be allocated to sub carrier groups is correlated to the number of transmission antennas so as to detect periodicity of the self-correlation characteristic of a reception SCH signal, thereby identifying the number of transmission antennas.

摘要： It is possible to provide a novel pilot transmission method which can calculate an accurate channel estimation value, a MIMO transmission device using the pilot transmission method, and a MIMO reception device which performs communication with the MIMO transmission device. The MIMO transmission device (100) includes a cyclic shift processing unit (150) which cyclically shifts a first pilot signal sequence spread by a spread code 1 and second pilot signal sequence spread by a spread code 2 with different shift amounts. The first pilot signal sequence and the second pilot signal sequence which have been cyclically shifted are transmitted from different transmitting antennas at the same pilot transmission symbol section. Thus, by changing the shift amount of the cyclic shift process executed on each pilot signal sequence spread by the respective spread codes, it is possible to improve the pilot separation accuracy at a reception side. This enables more accurate calculation of a channel estimation value.

摘要： In order to reduce interference between cells through hopping and use frequencies in a good propagation situation, a scheduler section 102 carries out scheduling for determining to which user data should be sent using CQI from each communication terminal apparatus, selects a user signal to be sent in the next frame and determines in which subcarrier block the data should be sent. An MCS decision section 103 selects a modulation scheme and coding method from the CQI of the selected user signal. A subcarrier block selection section 110 selects a subcarrier block instructed by the scheduler section 102 for each user signal. For the respective subcarrier blocks, FH sequence selection sections 111-1 to 111-n select hopping patterns. A subcarrier mapping section 112 maps the user signal and control data to subcarriers according to the selected hopping pattern.

摘要： A method is provided which improves reliability of channel estimation in a digital communication system by reducing the ambiguity in the recognition of received symbols evaluated for the channel estimation. A first plurality of bits is mapped to a modulation state according to a given Gray mapping of binary numbers to modulation states and plurality of bits transmitted. The plurality of bits is re-transmitted at least once, with a sub-set of bits contained in the plurality of bits inverted, and mapped to further modulation states according to the same Gray mapping. The bits to be inverted are determined in a way that the number of different vector sum results obtainable, for all combinations of bit values within the first plurality of bits, by adding vectors representing complex values of the first and further modulation states in a complex plane, is lower than the number of different modulation states within the Gray mapping.
