Blind adaptive spatial-temporal equalization algorithms for wireless communications using antenna arrays

Antenna arrays are used for diversity reception so as to improve the quality of wireless communication systems. To make full use of the information contained in each sensor, a spatial-temporal equalizer is used to remove intersymbol interference and mitigate the additive channel noise. This equalizer can be used in the wireless communication systems to improve the performance. This article introduces two blind adaptive algorithms for spatial-temporal equalization. Computer simulation demonstrates that the new algorithms converge faster than fractionally spaced constant-modulus algorithm (FS-CMA).
