    摘要: A fixed frequency dual downconversion receiver, comprises: an analog first downconversion and IF filter stage; means for one-bit coding of the downconverted signal; and means for second downconversion by digital subsampling. The receiver is particularly suitable for use in GPS applications.

    摘要: A fixed frequency dual downconversion receiver, comprises: an analog first downconversion (10) and IF filter stage (20); means for one-bit coding (24) of the downconverted signal; and means for second downconversion by digital subsampling (26,28). The receiver is particularly suitable for use in GPS applications.
