The evolving periodicity of the brightness of certain types of stars can now be described mathematically. "It can be difficult to explain the variations of the brightness of variable stars unless they ...

Here is a good example of CSP at work. Imagine two BPSK signals with different symbol rates and slightly different center frequencies. Looking at the combined BPSK signals - created with mksig.py -d, ...

Not all stars shine brightly all the time. Some have a brightness that changes rhythmically due to cyclical phenomena like passing planets or the tug of other stars. Others show a slow change in this ...

A newly developed method mathematically describes periodic changes in the brightness of stars. The model can also be applied to similar variable phenomena such as ...
