METHOD AND DEVICE FOR TRANSMITTING ULTRA WIDE-BAND FREQUENCY

摘要

The invention relates to a device and method for transmitting a binary data (c<SUB>i</SUB>) frequency in a transmission channel, wherein a signal generator generates a pulse signal (p<SUB>i</SUB>) whose length (t<SUB>i</SUB>) is shorter than the length of said binary data (c<SUB>i</SUB>), means generates at least one periodic signal whose frequency (f<SUB>j</SUB>) ranges according to predetermined conditions and is greater than a frequency (1/t<SUB>i</SUB>) which is inverse of the length (t<SUB>i</SUB>) of the pulse signal (p<SUB>i</SUB>), multiplying means multiplies said pulse signal (p<SUB>i</SUB>) by the periodic signal of the variable frequency (f<SUB>j</SUB>) and transmitting means transmits the pulse signal (p<SUB>i</SUB>.f<SUB>j</SUB>) obtainable by said multiplication.
