摘要： Multi-carrier transmission is performed without inserting a repetitive signal into guard interval periods. A transmitter provides guard interval periods by using a null signal to save transmission power and prevent the deterioration of the SN ratio. Delayed waves at the head of each received symbol cause high-frequency waves to occur and carriers to interfere with one another. Accordingly, a receiver adds a component following each received symbol to a delayed-wave component at the head of the received symbol. As a result, the delayed-wave component at the head of the received symbol and the added component become continuous in wave form and subcarriers do not interfere with each other.
摘要翻译： 执行多载波传输而不将重复信号插入保护间隔周期。 发射机通过使用空信号来节省传输功率并防止SN比的恶化来提供保护间隔周期。 每个接收到的符号的头部的延迟波导致高频波发生，并且载波彼此干扰。 因此，接收机将接收到的符号之后的分量添加到接收符号的头部的延迟波分量。 结果，接收符号的头部的延迟波分量和相加分量在波形上变得连续，并且子载波不彼此干扰。

摘要： A transmitting station side transmits a transmitting signal obtained by a process of segmenting transmission information into a plurality of frames, of encoding each frame, of power amplifying each encoded signal with different amplitude, and of interleaving all signals with each amplitude signal collected into one. A receiving station side reproduces of the above transmitting signal into original segmental frames by a process of de-interleaving the above transmitting signal, of successively decoding codes of the signal in descending order of SINR, and of re-encoding the decoded signal to successively cancel the re-encoded signal from the above transmitting signal.
