Frequency-hopping analysis circuit of receiving apparatus in wireless transmission system
First Claim
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.

Abstract
The present invention relates to a frequency-hopping analysis circuit of a receiving apparatus in a wireless transmission system, which includes an RF receiving circuit, a detection circuit, and a matching module. The RF receiving circuit receives an RF signal according to an initial frequency-hopping sequence to produce a baseband signal. The detection circuit detects the signal strength of the baseband signal, and identifies the corresponding piconet group of the baseband signal according to the estimated strength. Then, the matching module matches a preamble of the baseband signal according to a plurality of piconets of the corresponding piconet group of the baseband signal, and gives the corresponding piconet of the baseband signal. Thereby, the corresponding frequency-hopping sequence of the baseband signal is given and is transmitted to the RF receiving circuit for replacing the initial frequency-hopping sequence.
