Abstract:
The invention provides a system and method of generating a number of inputs to the mixer elements in a direct conversion (homodyne) receiver configuration using Virtual Local Oscillator (VLO) techniques. These generated inputs meet the requirement that they must have a fixed and stable phase-relationship, as well as being correctly related in terms of their power spectra relative to the operating radio (RF), intermediate (IF), and baseband frequencies of the system, and that when applied to the mixer elements they permit the mixer elements to create internally the effect of applying the Local Oscillator signal at a suitable frequency.
