摘要: The invention discloses a carrier frequency deviation estimation and compensation method of single-carrier domain balance system in great-frequency condition. comprises the following steps of: performing related operation received frame header repetitive sequence to obtain rough estimated value, open-loop processing on signal by use value; after compensation, through like demodulated constellation diagram; calculating rotary phase diagram fine feeding value back balancer part, closed-loop finish deviation. disclosed has characteristics large range deviation, high precision moderate algorithm complexity like, is particularly suitable for communication environment.
