Abstract

In order to analyze the ambiguity function of WiMAX signals and evaluate their suitability for passive radar, the first step should be the generation of WiMAX transmission signal, including random data generation, modulation, Space Time Block Coding (STBC), preamble generation for synchronization and channel estimation, frame combination and Orthogonal Frequency Division Multiplexing (OFDM) modulation. In this paper, WiMAX signal generation based on a Multiple-Input-Multiple-output (MIMO) OFDM testbed as well as detailed baseband signal processing algorithms are presented. Field trials and measurements based on the MIMO-OFDM testbed in different channel conditions have verified that the signal generation method and the adopted baseband signal processing algorithms are effective.
