Carrier Frequency Recovery with CPM Modulations
1997Continuous phase modulation (CPM) encompasses a class of signaling schemes that conserve and reduce signal energy and bandwidth at the same time. Furthermore, the signals in this class have a constant envelope and therefore are very attractive in radio channels employing low-cost non-linear power amplifiers.

Hardware Efficient Carrier Recovery Algorithms for Single-Carrier QAM systems
Advanced Photonics Congress, 2012This paper presents an overview on recent advancement of carrier synchronization techniques for optical systems using single-carrier quadrature-amplitude-modulation (QAM), with a special emphasis on a class of newly proposed multi-stage carrier phase recovery ...

Improved carrier recovery for signals affected by multipath fading
5th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, Wireless Networks - Catching the Mobile Future., 2002In this communication we consider the squaring loop carrier recovery scheme, with BPSK signals transmitted through a multipath channel. First starting from a multiray model for the multipath channel, the performance of the squaring loop is derived by suitably simplifying the channel model.
