摘要： A multicarrier transmitting apparatus includes a dividing section that divides transmit data into high-quality transmit data requiring good quality and ordinary transmit data other than the high-quality transmit data. A subcarrier allocation section rearranges the high-quality transmit data and the ordinary transmit data such that the high-quality transmit data is allocated to subcarriers in the vicinity of a center frequency in a predetermined frequency domain and the ordinary transmit data is allocated to subcarriers in the vicinity of both ends in the predetermined frequency domain. The subcarrier allocation section varies, in accordance with channel quality, a range of subcarrier to which the high-quality transmit data and ordinary transmit data are allocated. An orthogonal frequency division multiplexing section performs orthogonal frequency division multiplexing of the high-quality transmit data and the ordinary transmit data rearranged by said subcarrier allocating section.

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 transmit signal is spread by a plurality of spreading sections 103, 104, 105, and 106, using different spreading codes. A selection section 107 increases the number of spread signals to be output as the number of retransmissions increases. By this means, a retransmission signal spread by means of many spreading codes is code division multiplexed. As a result, retransmission signal error rate characteristics are improved on the receiving side by despreading this code division multiplexed signal using the same plurality of spreading codes as on the transmitting side, and selecting or combining the despreading results with the greatest correlation power thereamong. Also, since the degree of code multiplexing is increased proportionally as the number of retransmissions increases, retransmission signal error rate characteristics can be improved without lowering spectral efficiency unnecessarily.
摘要翻译：发射信号由多个扩展部分103,104,105和106使用不同的扩展码扩展。选择部分107随着重发次数的增加而增加要输出的扩展信号的数量。通过这种方式，通过许多扩频码扩频的重发信号被码分多路复用。结果，通过使用与发送侧相同的多个扩展码对该码分多路复用信号进行解扩，在接收侧改善重发信号误码率特性，并且在此之中选择或组合具有最大相关功率的解扩结果。此外，由于代码复用的程度随着重传次数的增加而成比例地增加，所以可以不用降低频谱效率来提高重传信号误码率特性。
