✦ Synopsis

This article concerns the problem of blind equalization. In practical situations, one must synchronize the receiver with the transmitter. The classical use of two separate algorithms, one for synchronization and one for equalization, does not work correctly as the channel interference increases. In such cases, one must prefer a joint estimation of the two unknown parameters (synchronization and equalization). Here, an original algorithm that jointly estimates the synchronism and the equalizer without any training period (blind estimation) is proposed. This algorithm is validated using both synthetic and real data. This study is limited to constant modulation schemes such as PSK.

The open literature is replete with claims about convergence benefits associated with second-order-statistics (SOS) blind channel estimation/equalization algorithms. At the same time, the literature is sparse in addressing robustness concerns of these algorithms. This paper is intended to motivate i
