DOI: 10.1109/tcsii.2022.3169224
Abstract: Fractional- $N$ frequency synthesizers are characterized by unwanted periodic components in their frequency spectra called spurs. In communications applications, spurs reduce the signal to noise ratio of the system; in clocking they add jitter; in… read more here.

DOI: 10.1109/tvt.2018.2865814
Abstract: Cellular networks are increasingly densified to deal with the fast growing wireless traffic. Interference mitigation plays a key role for the dense cellular networks. Successive interference cancellation (SIC) and fractional frequency reuse (FFR) are two… read more here.
