摘要： A configurable calculating circuit includes a multiplexer, a mixer and an accumulator. The multiplexer is for receiving input signals including at least a first and a second input signals, and selectively outputting at least one of the input signals. The mixer is for mixing a selected input signal outputted from the multiplexer with a local oscillation signal to generate a mixed signal. The accumulator is for accumulating the mixed signal to generate an accumulated signal. When the configurable calculating circuit is operated under a first mode, the multiplexer selects the first input signal, and the accumulator performs a first accumulating operation upon the mixed signal; and when the configurable calculating circuit is operated under a second mode, the multiplexer selects the second input signal, and the accumulator performs a second accumulating operation, different from the first accumulating operation, upon the mixed signal.

摘要： A gain control method is provided. In one embodiment, an amplifier amplifies a first signal according to a gain to obtain a second signal, and a converter converts the second signal to a digital signal. First, the gain is sequentially set to a plurality of gain values. A plurality of entropy values of the digital signal corresponding to the gain values is then calculated. A picked entropy value of the entropy values is then determined. The gain value corresponding to the picked entropy value is then determined as a picked gain value. Finally, the gain is set to the picked gain value for amplifying the first signal.

摘要： A method for determining a Doppler shift of a first signal is provided. First, a plurality of Doppler frequency hypotheses is combined to obtain a joint Doppler signal. The first signal is the correlated according to the joint Doppler signal and a plurality of code signals with phases corresponding to a series of code phase hypotheses to obtain a series of correlation results which are then examined to determine whether the Doppler shift does lie in the Doppler hypotheses. A fine Doppler search is then performed to determine the Doppler shift when the Doppler shift lies in the Doppler hypotheses.
