Serially Concatenated Overlapped Code Division Multiplexing (SC-OVCDM) system was presented. In this system, for input of OVCDM can be arbitrary modulated symbol, Trellis-coded modulation (TCM) code is firstly employed as outer code, OVCDM code with short constraint length is inner code, a symbol interleaver serially concatenates them. We employ serially(More)
The 3 August 2014 Ludian earthquake with a moment magnitude scale (Mw) of 6.1 induced widespread landslides in the Ludian County and its vicinity. This paper presents a preliminary analysis of the distribution patterns and characteristics of these co-seismic landslides. In total, 1826 landslides with a total area of 19.12 km 2 triggered by the 3 August 2014(More)
The development of landslide susceptibility maps is of great importance due to rapid urbanization. The purpose of this study is to present a method to integrate the subjective weight with objective weight for regional landslide susceptibility mapping on the geographical information system (GIS) platform. The analytical hierarchy process (AHP), which is(More)
Shortened BCH Codes are first used in SC-OVCDM system to overcome the disadvantage of higher error floor in a kind of SC-OVCDM systems in this paper, system model and key points of design for proposed system are described, there are two key points in system design: interleaving way and code rate of shortened BCH. Simulations and analysis demonstrate: block(More)
—Improved Overlapped Code Division Multiplexing system with high spectral efficiency, called Nonlinear OVCDM system, is proposed. Different from linear OVCDM system,the input alphabet of this system belongs to {0,1} and elements in the codeword matrix are real numbers. A nonlinear function and time varying codeword matrix is used to replace linear operation(More)
