Patent ID: 8639196

Claim:
A system, comprising: a first magnitude detector configured to generate an I data signal magnitude value of a sampled I data signal; a second magnitude detector configured to generate a Q data signal magnitude value of a sampled Q data signal; first calculating circuitry configured to calculate a phase shift angle φ I between first and second equal and constant or substantially equal and constant envelope constituents of the sampled I data signal; second calculating circuitry configured to calculate a phase shift angle φ Q between first and second substantially equal and substantially constant envelope constituents of the sampled Q data signal; first determining circuitry configured to determine in-phase and quadrature amplitude information of the substantially equal and substantially constant envelope constituents of the sampled I signal; and second determining circuitry configured 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.
