    摘要： A transmitter includes a time/frequency-domain converter (12) that converts a time-domain data signal to a frequency-domain data signal of a fixed number (N DFT ); a subcarrier llocator (14) that allocates the obtained frequency-domain data signal to any of (N IFFT ) subcarriers, the number of which exceeds the fixed number (N DFT ), the subcarriers being allocated in a predetermined transmission frequency Band; and a controller (18) that controls the subcarrier allocator (14) to allocate signals other than the data signal to subcarriers in an idle band to which the data signal is not allocated. By this, without the need for a plurality of time/frequency-domain conversion circuits with a large size, such as DFTs, frequency utilization efficiency (data transmission efficiency) is improved.

    摘要翻译： 发射机包括时域/频域转换器（12），其将时域数据信号转换为固定数目（NDFT）的频域数据信号; 子载波分配器（14），其将所获得的频域数据信号分配给数量超过固定数量（NDFT）的（NIFFT）个子载波中的任何子载波，所述子载波被分配在预定的传输频带中; 以及控制器（18），其控制副载波分配器（14）将不同于数据信号的信号分配给未分配数据信号的空闲频带中的副载波。 由此，不需要DFT等大尺寸的多个时域/频域转换电路，频率利用效率（数据传输效率）提高。
