چکیده
This paper provides a tutorial introduction to the constant modulus (CM) criterion for blind fractionally spaced equalizer (FSE) design via a (stochastic) gradient descent algorithm such as the constant modulus algorithm (CMA). The topical divisions utilized in this tutorial can be used to help catalog the emerging literature on the CM criterion and on the behavior of (stochastic) gradient descent algorithms used to minimize it.

On the Blind Equalization of Continuous Phase Modulated Signals Using a Constant Modulus Criterion
The use of a constant modulus (CM) criterion to achieve blind equalization of Continuous Phase Modulated signals is investigated in this paper. A characterization of the solutions is provided. It is shown that the constant modulus criterion may be, theoretically, unsuccessful because of the existence of undesired solutions.
متن کاملThe Generalized Constant Modulus Algorithm Applied to Multiuser Space-Time Equalization
The generalized constant modulus criterion and algorithm (GCMA) was proposed in [1] as a blind equalization technique for combating inter-symbol interference in single-user systems. In this paper we extend this concept for the blind separation and equalization of multiple users in presence of inter-symbol interference. The proposed criterion and algorithm can be viewed as a generalization of CM...

متن کاملImproving the Rate of Convergence of Blind Adaptive Equalization for Fast Varying Digital Communication Systems
The recent digital transmission systems impose the application of channel equalizers with bandwidth efficiency, which mitigates the bottleneck of intersymbol interference for high-speed data transmission-over communication channels. This leads to the exploration of blind equalization techniques that do not require the use of a training sequence. Blind equalization techniques however suffer from...
متن کاملNew adaptive blind equalization algorithms for constant modulus constellations
We present a new class of adaptive ltering algorithms for blind equalization of constant modulus signals. The algorithms are rst derived in a classical system identi cation context by minimizing at each iteration a deterministic criterion and then their counterpart for blind equalization is derived by modifying this criterion taking into account the constant-modulus property of the transmitted ...
