摘要：

This paper presents a new adaptive antenna-array structure using CMA/Fractional-Delay sequential blind beamforming for multipath correlated signals in environments, such as indoor confined or underground areas where the multipath problem is more severe than the co-channel interference. The new receiver uses a new synchronization approach for multipath propagation, based on combining a CMA adaptive antenna array and an adaptive fractional time delay estimation filter. This approach is designed to sequentially recover multipath rays based on adaptive time delay estimation for fractional time path arrival delays. The bit-error rate is evaluated for different operating conditions. Simulation results show the promising performance of the new adaptive antenna-array structure.
