摘要：Disclosure is a device and a method for estimating frequency offset in radioreceiver. Said device comprises: an analog-to-digital converter, a first storing meanshaving M elements; a multiplication means for performing multiplication between a

complex conjugate of delayed sampled element and a current sampled element; asecond storing means having N elements; an accumulating means for accumulatingoutput of said multiplication means; and a subtracting means for sequentially subtractingoutput of second storing means from output of said accumulating means; an estimatingmeans for generating said estimated frequency offset based on an output of saidsubtracting means. Furthermore, said method is achieved by utilizing the above device inthe same principle.
