Recommended by Ivan Cosovic This paper proposes two cyclostationarity-inducing transmission methods that enable the receiver to distinguish among different systems that use a common orthogonal frequency division multiplexing-(OFDM-) based air interface. Specifically, the OFDM signal is configured before transmission such that its cyclic autocorrelation(More)
It is becoming increasingly difficult to satisfy the growing demands on spectrum with the conventional policy of fixed spectrum allocation. To overcome this problem, flexible and dynamic spectrum sharing methods that can significantly improve utilization of the spectrum have gained increasing interest recently. In this paper, resource allocation in(More)
This paper proposes a multiuser detector that detects signals having different symbol rates, within a reasonable level of computational complexity. The proposed multiuser detector successively cancels undesired signals for each user in a received signal. In the proposed method, the undesired signals are band-limited using a band-pass filter for a desired(More)
The aim of the study is to identify the potential risk factors of cerebral infarction associated with thoracic endovascular aneurysm repair (TEVAR). TEVAR was developed as a less invasive surgical alternative to conventional open repair for thoracic aortic aneurysm treatment. However, outcomes following TEVAR of aortic and distal arch aneurysms remain(More)
—We introduce a truss decomposition algorithm for bipartite graphs. A subgraph G of a graph is called k-truss if there are at least k-2 triangles containing any edge e of G. By a standard breadth-first-search algorithm, we can compute the truss decomposition for large graphs. To extract a dense substructure that represents community in graph G, this method(More)
OBJECTIVES To better understand the relationship between mutation of the guanosine triphosphate cyclohydrolase I (GCH1) gene and the etiology of DYT5 dystonia and to accumulate data on the mutation in the Japanese population for genetic diagnosis of the disease. SETTING Japanese population. Patients Eight Japanese patients with suspected DYT5 dystonia(More)
