Many blind or semi-blind equalizers are implemented with the help of iterative algorithms, and therefore may require long convergence times or suffer from local minima. Closed-form block blind equalizers are attractive, even if they are suboptimal, since they can serve to initialize them. But they can perform better in time-varying contexts, that is on very short data blocks. The authors focused mainly on PSK modulations, including MSK and QPSK. The proposed algorithms are based on known instantaneous properties of such modulations
