Abstract
For the purpose of combating constant carrier envelope co-channel interference on a spread spectrum mobile link, a novelpolar adaptive A/D converter is analyzed and compared with the more familiar Cartesian form of the adaptive A/D. The polar A/D converter, operating in a noncoherent detection setting, is seen to exhibit fundamentally superior performance, even when the competing Cartesian converter is allowed to operate in a coherent detection mode. Very simple asymptotic performance formulas are given for both the polar and Cartesian forms.
