Joint clock recovery and baseband combining for the diversity radio channel

Multipath fading is one of the major impairments encountered in terrestrial digital radio. A common countermeasure to limit the outage time due to multipath is the space diversity technique, which takes its effectiveness from the low correlation between the field samples of two well separated antennas. A very simple and effective blind receiver is proposed for the diversity radio channel. The novelty of the present study is the application of the constant modulus algorithm to joint clock recovery and baseband combining. The effectiveness of our proposal relies upon the synergic action of clock recovery and adaptive baseband combining, which allows optimal equalization of the two-ray diversity channel
