Enhancement of the W-CDMA Scheme based on Parallel Matched Filters
نویسندگان
چکیده
The basic structure of the W-CDMA system is investigated first in this paper together with its characteristics which have been provided previously by the authors. The advantages of the W-CDMA are wide spreading and coherent detection with a pilot channel. The pilot channel is optimized to give the best performance of Bit Error Rate. New structure of W-CDMA receiver is then studied to increase transmission data rate and capacity of mobile communications. This structure, with parallel matched filter, has been proposed for synchronization and demodulation under multipath environments. Parallel matched filter is configured by analog MOS LSI instead of conventional digital components. The power consumption and dimension of the LSI are reduced by the combination of system and hardware approaches. Key-Words: Synchronization, Pilot signal, Matched filter, W-CDMA, Mobile communications.

متن کاملAdaptive Line Enhancement Using a Parallel IIR Filter with A Step-By-step Algorithm
A step-by-step algorithm for enhancement of periodic signals that are highly corrupted by additive uncorrelated white gausian noise is proposed. In each adaptation step a new parallel second-order section is added to the previous filters. Every section has only one adjustable parameter, i.e., the center frequency of the self-tuning filter. The bandwidth and the convergence factor of each secti...
