The spectrum of the square of a synchronous random pulse train
Nelson M. Blachman, S. Hossein Mousavinezhad · IEEE Transactions on Communications · 1990
Novel forms are derived relatively simply for the spectrum of the square of a synchronous random pulse train. The lines in the discrete part of the spectrum are useful for bit and carrier synchronization in digital communication systems, whereas the continuous part of the spectrum limits the signal-to-noise ratio available in any given bandwidth from the spectral lines. The application of the formulas derived and some conclusions are discussed.>
