The digital frequency-hopping (FH) transceiver and the method thereof can be applied to FH communication system with a short FH time. The transceiver employs a digital signal processing (DSP) in baseband (BB) circuits to implement FH without need to adjusting the RF carrier frequency. Wherein, the digital FH transmitter performs DSP on a digital BB transmission signal to frequency-hop between BB sub-bands corresponding to sub-bands of a channel, converts it into an analog signal, and then modulates the analog signal to the channel sub-bands for transmission. The digital FH receiver then performs carrier demodulation, analog-to-digital conversion and DSP on a received signal to regain the original digital BB transmission signal.
