PLL and zero crossing detection
The DFT does that, and is, so to speak, the grandmother of all frequency estimators; the peaks of the absolute spectrum would usually coincide with your signal's frequency, and their complex rotation …

upconverting a kHz/MHz signal to GHz
Is there any IC useful or should it be by PLL?
This question makes no sense. All the ICs that might make sense here contain at least one form or another of a PLL.
How?
Good! …

Non-coherent discriminator
That $\angle$ is "angle". As the text right below it indicates, it's the phase of a complex number, in this case the phase of the sum of squared $p_k$.
Your second question: I really don't think pseu …

Most efficient way to find single dominant frequency (without amplitude) in analog signal
The multibit reference signal is typically not sinusoidal, can have offset and substantial noise, but is expected to contain one dominant frequency.
Against offset, you'd practically always start yo …

BPSK based audio digital communication system
First of all: I'm 100% with Hilmar. I'm really not an acoustic expert, but I remember helping students build a minimal audio data transmission system, and the take aways are really these; you can, if …
