Adaptive Time Delay Estimation with Noise Suppression for Sinusoidal Signals - Circuits and Systems. MWSCAS 2002. Proceedings of the 2002 IEEE Midwest Symposium on

چکیده
A least mean square algorithm is devised for time delay estimation between noisy sinusoidal signals received at two spatially separated sensors. Two adaptive nite impulse response (FIR) lters whose coe cien ts are samples of a sine function are used for delay modeling as well as noise suppression. The convergence behavior and variance of the estimated delay are also derived. Computer sim ulations are presented to validate the theoretical derivations of the proposed estimator for static and linearly varying delays.

Based on the linear prediction property of sinusoidal signals, a closed form unbiased frequency estimator for a real sinusoid in white noise is proposed. The frequency estimate derives from minimizin g a constrained least squares cost function and it is simple to implemen t either in batch or recursive mode. The relationship of the proposed method with the well-known Pisarenko harmonic decompos...

متن کاملSmoothing the Control Action for NARMA-L2 Controllers - Circuits and Systems. MWSCAS 2002. Proceedings of the 2002 IEEE Midwest Symposium on
There have been many approaches to the use of neural networks in control systems, such as the NARMA-L2 Controller, introduced by Narendra and Mukhopadhyay. One disadvantage of this controller is that it often produces chattering in the control action. In this paper we investigate the addition of linear feedback to the NARMA-L2 controller in order to smooth the control action. We show that under...

Future wireless systems need extremely fast and flexible architectures to support varying standards, algorithms and protocols with data rates in the range of 10-100 Mbps. Software Defined Radios (SDRs) based on DSP-FPGAs are a widely proposed solution for these systems. However, these SDR solutions have not been able to meet real-time requirements. We propose a programmable architecture solutio...
