The Block-FFT based multiuser detection algorithm is investigated, and the complexity and performance of the proposed 8-point Block-FFT multiuser detector is compared to that of Cholesky decomposition based multiuser detector. The results indicate that the performance of the proposed 8-point Block-FFT algorithm is comparable to that of Cholesky decomposition algorithm, and the complexity is lower...
A network model using Self-organizing map (SOM) and Outputs Modifiable Radial Basis Function (OMRBF) is proposed to identify acoustic fault of underwater vehicles. This model integrates unsupervised SOM with supervised OMRBF to accomplish incremental learning. The outputs neurons of this model can be modified on-line, and SOM is utilized to determine the optimal number of hidden neurons. Experiment...
In this paper we present a new method of compensating for complex multipath channel fading in blind multiuser detection for DS-CDMA communication. This compensation allows for the use of different chip pulse shapes. The compensation is based on the incorporation of priors derived from the FFT of the pulse shape. The system employs detectors that incorporate methods of independent component analysis...
