Abstract: A frequency offset (FO) estimation method includes: sampling a frequency-modulated repetition-coded segment of a packet to generate a plurality of samples; obtaining a frequency deviation (FD) value for each of a plurality of target samples selected from the plurality of samples; and estimating an FO value through accumulating complete FD values of the plurality of target samples.

Abstract: A wireless communication device includes a receiver circuit, a phase shift control circuit, and a digital phase-locked loop (DPLL) circuit. The receiver circuit includes a down-converter circuit that is used to apply down-conversion to an input signal according to a local oscillator (LO) signal. The phase shift control circuit is used to generate a phase shift signal. The DPLL circuit is used to generate the LO signal locked to an initial frequency under a frequency-lock state. In response to the phase shift signal, the DPLL circuit is further used to make the LO signal have a different frequency without leaving the frequency-lock state.

Abstract: A wireless communication method includes: deriving a first received signal at a target channel from a first radio-frequency (RF) signal received through a first antenna; deriving a plurality of different parameters from signal strength of the first received signal; and performing a first packet detection operation for detecting if a packet is included in the first received signal by jointly considering the plurality of different parameters of the first received signal.
