    摘要: The present patent application discusses a frequency translation apparatus for altering the effective frequency of the phase information of an input signal (115). The input signal (115) has a first phase (.theta.(t)) and a first frequency (f.sub.i). The phase of the input signal is extracted and digitized at a second frequency (f.sub.o), forming a second N-bit digital phase signal (.theta.'(t))(311). The frequency translation apparatus generates a third digital phase signal (319) which approximates the difference between .theta.(t) and .theta.'(t). Then, the frequency translation apparatus combines the second digital phase signal and the third digital phase signal, forming a fourth digital phase signal (307) substantially approximating the first phase signal.

    摘要: A demodulator (414) for improving bit error rate performance where alternating bit patterns produce the worst occurrences of bit errors. The demodulator (414) consists of a zero threshold comparator circuit (502), a first threshold detector circuit (508), and a second threshold detector circuit (504). The zero threshold comparator circuit (502) receives a frequency information signal and slices it into a plurality of bits (522). The first threshold detector circuit (508) compares the frequency information signal to a predetermined threshold, which is selected to optimize bit error rate performance. The second detector threshold circuit (504) is used to ensure that an alternating bit pattern has occurred. The demodulator (414) also includes a control device circuit (516) for coupling the plurality of bits (522) from the zero threshold comparator (502) to the output of the control device as a decision output signal (416) when the frequency information signal falls outside of either the first or second detector thresholds (508), (504). If the frequency information signal falls within both thresholds of the detector devices then the decision output signal (416) for the control device (516) is formed by inverting the bit decision from the previous bit interval.
