Detailed Description

Mueller and Müller (M&M) based clock recovery block with complex input, complex output.

This implements the Mueller and Müller (M&M) discrete-time error-tracking synchronizer.

The complex version here is based on: Modified Mueller and Muller clock recovery circuit:

G. R. Danesfahani, T.G. Jeans, "Optimisation of modified Mueller and Muller algorithm," Electronics Letters, Vol. 31, no. 13, 22 June 1995, pp. 1032 - 1033.
