Abstract： Orthogonal Frequency Division Multiplexing （OFDM） is widely used in broadband mobile communicationdue to its high spectrum utilizationand resistance to multipath fading.However，in high-speed mobile environments， OFDM systems willface time-domain selective fading between subcarriers，which prevents some subcarriers from being correctly recovered，resulting indata lossand increasing thesystem's errorrate.Bycombining Walsh Hadamard Transform （WHT） with OFDM， WHT-OFDM technology can utilize the orthogonality property of WHTto reduce interference between subcariers， thereby improving the robustness of the system in high-speed mobile environments.This technology integrates the orthogonal signal procesing capabilityofWHTand thehigh frequency efficiency of OFDM，providing a more reliable solution for broadband wireless communication.
