The invention provides a method for hiding redundant information in G.711 phonetic coding. Pre-treatment is carried out before a phonetic packet is coded so that the phonetic packet is provided with hidden information insensitive to human ears, the information contains main features of adjacent other phonetic packets, then normal G.711 mode is used for coding and sending, the same back propagation is carried out for decoding and post-treatment at a receiving end, thus obtaining the original phonetic information. When the data packet is lost, the main phonetic features of the lost packet can be obtained from the adjacent data packets, thus restoring the main phonetic data of the lost packet. While for the device not knowing the hidden algorithm, normal G.711 mode can be directly used for decoding to obtain phonetics approaching the original state, thus the system can be compatible with G.711 code, and can greatly improve the capability of packet losing resistance of phonetic communication and improve communication quality.

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.
