A device for the frequency modulation and - demodulation of a frequency-selective baseband with the reinforcement of the frequency - diversity and device for transmitting and receiving with the use of the same

摘要

Frequency modulation in front of the direction for a frequency-selective baseband with frequency - diversity, wherein the frequency modulation comprises in the direction of:a transmission rates - control unit, which a data transmission rate and a repetition transmission number in accordance with a communication channel environment controls;a data generator, the same serial data corresponding to the repetition during transmission of numbers according to the control of the transmission rates - control unit outputs repeated;a serial / parallel - converter which converts the output of the data generator converts the serial data into parallel data; anda frequency-selective spreader, which, corresponding to the corresponding to the repetition during transmission of numbers according to the control of the parallel converted data transmission rates - control unit selects a frequency-selective spread code.
