    • In a communication method for transmitting a multi-path characteristic measurement signal and a plurality of data transmission signals, the multi-path characteristic measurement signal and data transmission signals are caused to become signal sequences that are formed by a plurality of coefficient matrixes and orthogonal to each other in the matrixes and that include at least one common coefficient sequence in the column or row direction; and the multi-path characteristic measurement signal formed by a coefficient matrix is caused to become the same signal sequence formed by the common coefficient sequence. According to this, in a simultaneous transmission of the multi-path characteristic measurement signal and data transmission signals by use of a transmission data spread modulation using a spectrum spread, the transmission standby time and signal reception time required for transmission of multiple data transmission signals can be shortened and the scale of the reception processing apparatus can be reduced.

    • A coefficient string of a spread sequence is successively shifted by one pitch and the transmission data is multiplied by these plurality of coefficient strings so as to form a plurality of transmission data. The plurality of transmission data formed are added to form a transmission data string. Alternatively, a coefficient string of the spread sequence is multiplied by transmission data and successively shifted by one pitch so as to form a plurality of transmission data. The plurality of transmission data formed are added to form a transmission data string. Moreover, the transmission data is multiplied by a coefficient string of the spread sequence so as to form a finite length signal. This finite length signal is repeated infinite times to form an infinite length signal. From this infinite length signal, transmission data longer than the coefficient string is cut out to form a transmission data string. Thus, by building the transmission data into the spread sequence, it is possible to reduce spread of the signal amplitude in the transmission data modulation by the spectrum spread and reduce the dynamic range of the reception side.
    • 扩展序列的系数串依次移位一个音调,并将发送数据乘以这些多个系数串,形成多个发送数据。 添加形成的多个发送数据,形成发送数据串。 或者,将扩展序列的系数串乘以发送数据,并依次移位一个音调,以形成多个发送数据。 添加形成的多个发送数据,形成发送数据串。 此外,传输数据乘以扩展序列的系数串,以形成有限长度信号。 该有限长度信号被无限次重复以形成无限长度信号。 从该无限长信号中切出比系数串长的发送数据,形成发送数据串。 因此,通过将发送数据构建到扩展序列中,可以通过频谱扩展来减少发送数据调制中的信号幅度的扩展,并且减小接收侧的动态范围。

    • In a transmitted-data modulation by spread spectrum, attention is given to not spread series themselves but transmitted-data string, thereby providing alienation of the periodic spectrum of transmitted signals, reducing extension of the signal amplitude, and reducing the dynamic range of an amplifier on the receiving side. The transmitted-signal producing method comprises a step of producing a plurality of transmitted data by multiplying transmitted data by coefficients of a predetermined coefficient string, and a step of producing a transmitted-data string by adding zero data of a predetermined length between ones of the plurality of transmitted data as multiplied by the coefficients.
