Can anybody recommend a good source for material of Gaussian and Complex Gaussian wavelet? Please share the link if possible.

    $\begingroup$ Welcome to SE.DSP. Some of us are able to do so, yet could you tell us more about why you need it, and what you have found so far? $\endgroup$ – Laurent Duval Aug 31 '19 at 13:56
  • $\begingroup$ I need to prepare a presentation on these two wavelets to present in front of class.And it is also included in my syllabus so I have to study them for my end term exams. researchgate.net/publication/… I have found only this much and nothing on complex gaussian wavelet. $\endgroup$ – Mayank Singh Aug 31 '19 at 16:59

The notion of "Gaussian wavelet", whether real or complex, is not clear from the literature. Indeed, the Gaussian has a positive average, while wavelets are (or should be) zero-mean (to satisfy the admissibility condition).

Two standard wavelets may suit your need:

Their complex extensions, or real restrictions, are relatively natural.
