Nonlinear Programming Based Preamble Design for OFDM Systems
Nonlinear Programming Based Preamble Design for OFDM Systems
摘要
Abstract
A new preamble structure and design method for orthogonal frequency division multiplexing (OFDM) systems is described, which results a two-symbol long training preamble. The preamble contains four parts, the first part is the same as the third, and the four parts are calculated by using nonlinear programming (NLP) model such that the moving correlation of the preamble results a steep rectangular-like pulse of certain width, whose step-down indicates the timing offset Simulation results in AWGN channel are given to evaluate the performance of the proposed preamble design.关键词
