Due to Detlef _A hint, the phase and amplitude are perfectly aligned, which resulted in an improvement.I don’t understand why the amplitude should have a wider...
Your assessment motivates me to keep looking for the catch in polar modulation using an NCO.So far, it’s just a simulation; there are neither amplifiers nor nonlinearities....
I’ve also tried my hand at correction algorithms and had similar experiences: every adjustment to the phase worsened the result.By unwrapping the atan2 before...
The videos demonstrate very good, distortion-free audio quality. It seems you've largely solved the phase calculation problem.But what do you mean by “manual intervention”?...
There are very few documented transceivers that use polar modulation. One of them is the uSDX project.https://github.com/threeme3/usdxUnfortunately, the SSB signal...
Thanks for the tip. In addition to slightly better phase correction at the -pi/+pi discontinuity of arctan2(), I optimized the timing between phase and magnitude....
For the simulation, I used two different test signals: first, the opening announcement from a TV news program, band-limited to 200 Hz–2700 Hz; and second, a two-tone...
