| 主权项 | 1. A method of receiving signals by an FSK (frequency shift keying) receiver, the method comprising: receiving an FSK signal, wherein the FSK signal comprises a silence part; converting the FSK signal into a phasor including amplitude and phase; recovering a data bit from the phasor; eliminating an interference signal from the FSK signal by using the phasor converted from the silence part; and estimating a CFO (carrier frequency offset) by using the phasor. | ||
