Solution to Tactical Wideband Network Waveform Physical Layer
摘要
Abstract
This paper analyzes the core architecture and system of groud mobile radio( GMR) waveform, presents the tactical wideband network waveform( WNW) physical layer scheme in accordance with its mil-itary application trend,and discusses two key technology of physical layer waveform based on orthogonal frequency division multiplexing(OFDM). First,for peak-to-average power ratio(PAPR) suppression,the problem of traditional iterative clipping and filtering technique requiring a high number of iterations is solved by interior-point optimization algorithm based on raised convex optimization theory. Second, the channel estimation technology based on non-statistical information is used to replace the original minimum mean squared error ( MMSE ) methods. Simulation results show that the performance of new method is roughly equal to that of MMSE method,but it avoids calculating the channel statistics and matrix inversion with a large number of complex calculations. The results of system simulation demonstrate the excellent per-formance and the validity of the scheme and solution to key technology.关键词
