TRANSMITTER, TRANSMITTING METHOD, RECEIVER, AND RECEIVING METHOD

摘要

A transmitter which alleviates the effect of delayed waves without reducing the transmission efficiency to prevent degradation in overall throughput. In the transmitter for transmitting the SC-FDMA signals, a data realignment section (130) assigns a signal with better error characteristics or a signal requiring no high error characteristics toward the end of a symbol length of the SC-FDMA signal to obtain a time-region signal, and a time/frequency converter section (140) forms the SC-FDMA signal using the time-region signal. This allows the signal to be realigned by selecting the symbol end subject to the effect of delayed waves and the symbol center less subject to the effect of delayed waves out of the SC-FDMA symbol length. As a result, the influence of an error at the symbol end subject to the effect of delayed waves on the overall packet is reduced to prevent degradation in overall throughput.
