In each time level we use techniques coming from interpolatory multiresolution analyses for detecting discontinuities of the solution. The adaptive scheme uses first order upwind flux computation in the immediate neighbourhood of these irregularities. Since the differential equation holds in the smoothness domain, we follow the characteristics in the time marching procedure at grid points in that domain.","PeriodicalId":165081,"journal":{"name":"38th Midwest Symposium on Circuits and Systems.

This paper investigates the convergence properties of the constrained frequency-domain block LMS (CFBLMS) algorithm and the unconstrained frequency-domain block LMS (UFBLMS) algorithm when applied to truncated Volterra systems. As shown by previous work, the range of stability for the UFBLMS algorithm for linear systems is 1/2 of that with the CFBLMS algorithm. This work verifies that this relationship between the UFBLMS algorithm and the CFBLMS algorithm is valid for truncated Volterra systems as well. This paper further shows through simulation results that the performance of the UFBLMS algorithm is comparable to the CFBLMS algorithm if the step size is adaptive.","PeriodicalId":165081,"journal":{"name":"38th Midwest Symposium on Circuits and Systems.

They accomplish continuously repeated retransmission to overcome noisy channel error condition and provide buffer at receivers, aiming at improving their throughput efficiencies. The first scheme is a point-to-multipoint version of the single destination Morris's GB(N). The other one results from slight modifications in the retransmission procedure. After the continuously repeated retransmission, the transmitter sends m (m/spl ges/1) copies of messages sent in advance and received in error. Numerical results show that the proposed modification significantly improves the throughput efficiency. Moreover, the proposed protocols outperforms many other multidestination GB(N) schemes.","PeriodicalId":165081,"journal":{"name":"38th Midwest Symposium on Circuits and Systems.
