摘要： A control section (110) recognizes the type of data included in a transmission signal and outputs a control signal (C1) to an S/P conversion section (101) and a spreading control section (107). The S/P conversion section (101) apportions a specific type of data output from the control section (110) to different transmission systems. Spreading sections (102, 103) carry out spreading processing on the specific type of data output from the S/P conversion section (101) with different spreading codes assigned thereto under the control of the spreading control section (107). The data output from the spreading sections (102, 103) is transmitted by radio through addition sections (104-1, 104-2), transmission sections (105-1, 105-2) and antennas (106-1, 106-2). In this way, it is possible to improve the reception performance on the receiving side for specific data while maintaining the transmission efficiency of an MIMO communication system.

摘要： A transmission control section 101 temporarily stores a transmission signal, outputs the stored transmission signal to a coding section 102 and outputs transmission timing information to a counter section 107. A preamble insertion section 104 inserts AGC preambles corresponding to the number set by a preamble number control section 110 into the transmission signal. The preamble number control section 110 compares a transmission time interval input from a subtraction section 109 with a threshold, decides to insert ten AGC preambles into the transmission signal when the transmission time interval is equal to or greater than the threshold and decides to insert five AGC preambles into the transmission signal when the transmission time interval is smaller than the threshold. By so doing, it is possible to make the transmission efficiency compatible with the error rate characteristic.

摘要： An OFDM-CDMA transmission apparatus may include a first spreader that carries out spreading processing on a plurality of transmission signals using different spreading codes, respectively. A second spreader carries out spreading processing on at least one known signal using a spreading code different from the spreading codes employed by the first spreader. A frequency division multiplexer breaks down the transmission signals spread by the first spreader and the known signal spread by the second spreader into individual chips and subjects these chips to frequency division multiplexing, thereby assigning one chip data signal string per subcarrier. The frequency division multiplexer operates such that information from each of the plurality of transmission signals and the known signal is multiplexed into every chip assigned to a different subcarrier. After the chips are assigned to the subcarriers, they are transmitted by a transmitter.

摘要： Modulation section 201 performs modulation processing on transmission data. Mapping control section 202 controls mapping of the baseband signal onto the subcarriers so that the important information conventionally transmitted by one subcarrier is transmitted by two subcarriers and one of the two subcarriers should be the subcarrier with a carrier frequency signal of frequency 0 which was conventionally not used. IFFT section 203 performs IFFT processing on the modulated transmission data. Transmission section 204 performs transmission processing on the IFFT-processed transmission data and transmits the processed transmission data from antenna 205.

摘要： A communication system enabling significant reduction in delay in handover between MAPs without increasing the number of MAPs to install. In the communication system, MAP(101) issues a Router Advertisement to AR(111) to AR(118). Particularly, MAP(101) assigns a plurality of Router Advertisements of a source of care-of address (RCOA) to register with HA to AR(118) of a cell on either side of a boundary of areas for each MAP. MN(107) receives a Router Advertisement transmitted from AR that is a communicating party among AR(119) to AR(126), and using the Router Advertisement, generates care-of addresses, RCOA and LCOA. AR(111) to AR(118) transmit the Router Advertisement RA generated by MAP(101) to MN in communication. Further, AR(111) to AR(118) transmit the care-or-addresses, RCOA and LCOA, issued from MN(107) to MAP(101).

摘要： A receiving section (102) performs a wireless receiving processing over a signal that is received through a receiving antenna (101), and output thereof to a propagation path compensation section (103) and an interference compensation section (104). The propagation path compensation section (103) conducts a propagation path compensation for the received signal, based on the result of the propagation path estimation. The interference compensation section (104) performs a propagation path estimation, and output this results to a controller section (105), and also performs a MIMO separation processing and output the separated received signals to a selecting section (106). The selecting section (106) selects one of the signals output from the propagation path compensation section (103) and the interference compensation section (104) under the control of the controller section (105) and output thereof. The controller section (105) controls the selecting section (106), based on the result of the propagation path estimation. A demodulating section (107) and a decoding section (108) performs a demodulating and decoding of the received signals. Having this configuration, in MIMO communication, an error rate characteristic in the receiving side can be improved even under the environment, in which an interference compensation error becomes larger.

摘要： A turbo encoding section 102 turbo-encodes transmission data, outputs systematic bit data to a first modulation section 103a and outputs parity bit data to a second modulation section 104. The first modulation section 103a always QPSK-modulates systematic bit data. The second modulation section 103b adaptively modulates parity bit data. The control section 101 outputs a control signal for carrying out 16 QAM modulation to the second modulation section 103b when the RSSI value is equal to or higher than a threshold and outputs a control signal for carrying out QPSK modulation to the second modulation section 103b when the RSSI signal value is less than the threshold. In this way, it is possible to further make the error rate characteristic compatible with the transmission efficiency.

摘要： A wireless communication apparatus and a receiving scheme selection method are provided for improved overall system throughput. SIR measurer (106) measures the SIR of a known signal. Doppler frequency detector (108) detects the Doppler frequency from the received signal and measures the Doppler shift amount.
