I think the question must be corrected as ksamples, or Msamples. It varies according to how many samples the system can process in real-time, modulation degree ($m$), and oversampling factor ($OS$). For digital communication systems, typically, receivers require more processing power when compared to transmitters. Therefore, the bottleneck will probably be ...

Let us assume that you have a list of sampled I/Q data streams. The answer to your question may be two-fold. Firstly, are you trying to obtain the instantaneous or frequency of your carrier? Let us assume that you are trying to obtain inst. frequency. Then, first calculate the phase of your samples by simply performing $\phi(k) =\tan^{-1}(s_I(k)/s_Q(k))$. ...
