Abstract
A circuit is provided comprising detector circuitry, calculating circuitry, and determining circuitry. The detector circuitry is figured to generate an I data signal magnitude value of a sampled I data signal and a Q data signal magnitude value of a sampled Q data signal. The calculating circuitry is configured to calculate a phase shift angle φbetween first and second equal and constant or substantially equal and constant envelope constituents of the sampled I data signal and to calculate a phase shift angle φbetween first and second substantially equal and substantially constant envelope constituents of the sampled Q data signal. The determining circuitry is configured to determine in-phase and quadrature amplitude information of the substantially equal and substantially constant envelope constituents of the sampled I signal and to determine in-phase and quadrature amplitude information of the first and second substantially equal and substantially constant envelope constituents of the sampled Q signal.
