Abstract
A transmitting circuit, a transceiver, a communication system, and a method for transmitting data. The transmitting circuit includes a digital interface circuit configured to obtain, in a predetermined bandwidth, data to be sent, and decompose the data into N parallel sub digital signal flows; a digital modulation circuit configured to modulate the N sub digital signal flows to obtain N modulated signals; a frequency relocation circuit configured to perform frequency relocation on the N modulated signals; a synthesizer configured to modulate M modulated signals of the N modulated signals that have undergone frequency relocation into a bandwidth signal; a digital to analog converter configured to receive the bandwidth signal, and perform digital to analog conversion on the bandwidth signal to obtain an analog signal; an up-conversion circuit configured to receive the analog signal, and convert the analog signal into a radio frequency signal.
