Title:

A signal transmission device and a multicareer communications system

Document Type and Number:

Japanese Patent JP6202218

Kind Code:

B2

Abstract:

A signal transmission apparatus and multicarrier communication system. The signal transmission apparatus includes: a first receiving unit configured to receive a probe signal transmitted by transmitting end; wherein, the probe signal is generated according to characteristics of recommended signal configuration obtained by previous one or more times of signal to noise ratio probing; a first processing unit configured to probe a channel signal to noise ratio according to the probe signal; a first determining unit configured to determine transmission signal configuration and signal transmission performance according to a final channel signal to noise ratio obtained by multiple times of signal to noise ratio probing; and a first transmitting unit configured to transmit the transmission signal configuration and the signal transmission performance to the transmitting end, so that the transmitting end transmit an actual transmission signal according to the transmission signal configuration and the signal transmission performance. With embodiments of the present disclosure, accuracy of probing a nonlinear channel signal to noise ratio is improved, and reliability and stability of the communication system are guaranteed.
