1. A frequency-hopping analysis circuit of a receiving apparatus in a wireless transmission system, comprising:

  • a radio-frequency (RF) receiving circuit, receiving an RF signal transmitted by a transmission apparatus of the wireless transmission system according to an initial frequency-hopping sequence, and down-converting the RF signal to produce a baseband signala detection circuit, detecting the signal strength of the baseband signal, and identifying the corresponding piconet group of the baseband signal according to the estimated strength; and

    a matching module, matching a preamble of the baseband signal according to a plurality of piconets of the corresponding piconet group of the baseband signal, giving the corresponding piconet of the baseband signal, and giving the corresponding frequency-hopping sequence of the baseband signal, which is transmitted to the RF receiving circuit for replacing the initial frequency-hopping sequence.
