On the average over many realizations of the sequence, the frequencies of each word in the original text and in its random version were the same but, in the latter, word ordering was determined by chance and lacked any linguistic origin.
Figure13a shows the behavior of the proposed estimator in a realization of the transmission sequence.
Each path in the tree represents a possible realization of the transmitted sequence.
The principle of this iterative process is to perform permutations on the R l matrix rows to obtain a new virtual realization of the received sequence.
On each branch of the tree, MP, OMP, and BP are first used to estimate the sparse channel using the realization of the coded sequence associated with a path.
In the tree structure of the SA, each path represents a possible realization of the transmitted sequence; the MA can be used to estimate the channel sparsity along each path.
In agreement with other recent studies, we find the realization of these sequences to be very variable.
We thank C. Robert (Unité des Rickettsies, Marseille) for the technical realization of the GS20 sequences as well as M. Quadroni and the proteomic facility of the University of Lausanne for assisting with mass spectrometry analyses.
The first step is to generate the relative price data { x n = c n + 1 c n, n ≥ 1 }, which are a realization of the relative price sequence { X n = C n + 1 C n, n ≥ 1 }.
The last row of graphs shows the average results across 10 realizations of the workload sequences, including the four shown as Workloads 1 through 4. Figure 1 "Laptop" workload.
