摘要： A communications system for communications by a multicarrier transmission mode between a plurality of communications apparatuses (10, 20) wherein an overall frequency band assigned to the communications system is divided into a plurality of frequency bands each having a constant bandwidth (for example band 1 to band 4) and a specific band (for example band 1) among these divided bands is used to transmit used frequency band information and thereby determine the assignment of the remaining bands (band 2 to band 4) to be used between said communications apparatuses. Here, the specific band is defined as a main band for transmitting control channel information including said used frequency band information and also data channel information. The main band may also be added with an extension band for transmitting further data channel information. Further, the main band and extension band can be changed in the frequency band used along with time or can be changed in the number thereof. Both of the main band and the extension bands are preferably used by multiplexing by some of communications apparatuses.
摘要翻译：一种用于在多个通信设备（10,20）之间通过多载波传输模式通信的通信系统，其中分配给所述通信系统的总频带被划分为多个频带，每个频带具有恒定的带宽（例如频带1到频带4）和这些划分频带中的特定频带（例如频带1）用于发送所使用的频带信息，从而确定要在所述通信装置之间使用的剩余频带（频带2至频带4）的分配。这里，特定频带被定义为用于发送包括所使用的频带信息的控制信道信息以及数据信道信息的主频带。主频带还可以添加有用于发送另外的数据信道信息的扩展频带。此外，主频带和扩展频带可以随时间变化使用的频带，或者可以改变其数量。主频带和扩展频带都优选地通过一些通信装置进行复用来使用。

摘要： In the mobile communication, a distortion compensation amplifying apparatus is provided. In a predistortion-type distortion compensation amplifying apparatus (9), a signal amplitude change processing unit (10) comprises an odd-power component calculating unit (14) extracting a power component of odd order of an amplitude quantity contained in a signal to be transmitted and outputting it, a coefficient information outputting unit (15) being operable to select one of plural pieces of coefficient information based on a signal from the outside and output it, a multiplying unit (16) multiplying a signal outputted from the odd-power component calculating unit (14) by coefficient information from the coefficient information outputting unit (15) and outputting an attenuation signal, and an adding unit (17) subtracting the attenuation signal from the signal to be transmitted and outputting a result, thereby making an amplifier operate within a range not exceeding a saturation region thereof, decreasing a spurious signal, decreasing an adjacent channel power, and enabling distortion compensating operation even if a frequency of reference to the memory is decreased.

摘要： Sialic acid binding proteins, sialic acid-binding peptides and sialic acid containing oligo-saccharides are active ingredients of a novel bacterial enterotoxin neutralizer and interfere with the binding of enterotoxins, including cholera toxin, to receptors so as to exert an effect of neutralizing the toxicity, thus being utilized as an effective neutralizer and are safe and available cheaply and abundantly from by-products produced during the processing of cow's milk which renders the enterotoxin neutralizer economically advantageous for commercial use.
