The invention provides an OFDM communication system pilot frequency design method and system based on double standards, and the scheme comprises the following steps: step (1), determining a pilot frequency symbol position index by taking a minimum sampling matrix cross-correlation as a target based on an available carrier set in an OFDM communication system and a cross-correlation principle of a compressed sensing algorithm; (2) determining a power value of a pilot symbol at each pilot carrier position based on the obtained pilot symbol position index and a total correlation principle of a compressed sensing algorithm; and (3) iteratively executing the steps (1)-(2) for a first threshold number of times, and selecting the corresponding pilot symbol position index and the power value of the pilot symbol when the total correlation is minimum as a pilot design result of the OFDM communication system. 本公开提供了一种基于双标准的OFDM通信系统导频设计方法及系统，所述方案包括步骤步骤(1)：基于OFDM通信系统中的可用载波集合及压缩感知算法的互相关原理，以采样矩阵互相关最小为目标确定导频符号位置索引；步骤(2)：基于获得的
