Previous results at this level of generality linked convergence only to within a neighborhood of the optimum filter. Based on the adaptive scheme, two new theorems are established in a stochastic environment for which the adaptive EC filter converges in mean square sense and with probability one to the noiseless optimum filter for a fixed step-size and a decreasing sequence of step-sizes, respectively. Numerical examples involving pulse compression Barker-coded signal are studied for solving the EC filtering problem.","PeriodicalId":6422,"journal":{"name":"2000 IEEE International Symposium on Circuits and Systems.

After the acquisition process, the SPLL either reaches the desired fixed point or gets into false lock, depending on the initial conditions. In every implemented circuit, the development of false lock has to be prevented. Although the false lock problem was reported earlier, an exact model to describe the behavior of SPLL in false lock has not yet been published. This paper propose a phenomenological model to explain why the false lock can develop and to describe the operation of SPLL in false lock.","PeriodicalId":6422,"journal":{"name":"2000 IEEE International Symposium on Circuits and Systems.

A new class of DD representation, called Register-Oriented DDs (RODD) is introduced. The RODD model appears to be an efficient and compact representation of the system behavior for the high-level cycle simulation. In order to fully exploit the advantages of RODDs a new simulation algorithm, which is a combination of cycle-based forward event-driven and recursive back-tracing techniques is proposed. The characteristics of the simulation algorithms used to efficiently execute the evaluation of the DD network are discussed. Further the experimental results carried out on the real case examples demonstrating the gain in simulation performance of the proposed approach and a comparison of four cycle-based simulation algorithms are presented. Additionally, a comparison with the commercial event-driven and cycle-based HDL simulation tools is included.","PeriodicalId":6422,"journal":{"name":"2000 IEEE International Symposium on Circuits and Systems.

The vocoder exploits the interpolation property so that the fine quality in synthesized speech is obtained even though the bit rate is as low as 1.6 kbps. Two novel methods including pitch detection and LSP decoding which are suitable for VLSI implementation are also proposed. The heuristic pitch detection algorithm avoids the heavy computational load introduced by the traditional normalized autocorrelation method. The memory storing triangular function value is no longer needed after adopting the new LSP decoding process. The chip is designed with area effective feature and is suitable for stand alone application.","PeriodicalId":6422,"journal":{"name":"2000 IEEE International Symposium on Circuits and Systems.

In addition to lack of support of high quality passives in digital CMOS, use of passive devices causes problems with area, thermal noise of resistance, process variation, mismatch of capacitances, and inability to scalable designs. Consequently current high speed clock recovery circuits are implemented mostly in bipolar technology or other passive friendly technology. However, these technologies are not well-suited to the higher levels of integration needed for \"systems on a chip\". Also, current technology emphasis is shifting from increasing the operation speed of components to reducing their size, power consumption, and cost to eliminating the need for adjustment and trimming. These goals can be achieved by using fully passive component-free monolithic CMOS circuits. In this paper, we present a method for implementing a passive component filter which can be used in clock recovery circuit or PLLs.","PeriodicalId":6422,"journal":{"name":"2000 IEEE International Symposium on Circuits and Systems.
