Figure 2 shows the BER comparison of our code with Chusing’s code [7] and Zhang’s code [1] for the M = 4, N i = 2, N r = 1, N t = 2 case in the IEEE 802.15.3a UWB channel model CM4

Upon reception of a valid write command (CMD24 or CMD25 in the SD Memory Card protocol), the card will respond with a response token and will wait for a data block to be sent from

In particular, we present a linear-time algorithm for the k-tuple total domination problem for graphs in which each block is a clique, a cycle or a complete bipartite graph,

To compare different models using PPMC, the frequency of extreme PPP values (i.e., values \0.05 or .0.95 as discussed earlier) for the selected measures was computed for each

Bingham & Sitter (2001) used the usual minimum-aberration criterion for unblocked designs to compare split-plot designs, but since it often leads to more than one

Convergence of the (block) coordinate descent method requires typi- cally that f be strictly convex (or quasiconvex or hemivariate) differentiable and, taking into account the
