摘要： An apparatus and method for estimating and compensating sampling frequency offset are disclosed. Particularly, a linear mathematical scheme is employed to calculate the related phase difference for saving use of multipliers and storage circuit used for sampling frequency offset estimation and compensation in the conventional art. The preferred embodiment of the invention has a first step to receive signals by the offset estimating circuit. Next, the phase value for each signal is calculated, and the pilot signal therein is retrieved. Next, a phase difference is obtained by subtraction operation between the received symbols and the delayed pilot symbols. And a circuit for storing the phase differences is incorporated. Next, a phase difference between the adjacent symbols is obtained by accumulating the phases and processing the least-error-sum-of-squares operation. Therefore, an estimation value of the sampling frequency offset of a communication system is obtained, and further to compensate the offset.

摘要： An apparatus and a method for adaptively calculating a start position of a series of symbols are provided. The method is applied to a frame synchronization circuit that implements the apparatus for calculating the symbolic start position of a packet-switching communication system. Even under the situations such as higher frequency offset, the frequency offset value approaching zero or unstable frequency offset, the frame synchronization circuit using the claimed method still can estimate the symbolic start position. The preferred method includes a first step of retrieving the signals in a unit of packets, and calculating their delay correlation value. Next, a control circuit is incorporated to retrieve multiple groups of symbols, and to set the parameters of the systems as a basis for identifying the system's property. After that, it's to estimate the symbolic start position.
