Differential Modulation is a non-coherent modulation technique which is used to solve the uncertainty channel problem. The most popular Differential Unitary Modulation technique uses a Space-Time Block Code (STBC) to improve the performance of Differential Modulation technique in multi-in multi-out (MIMO) system. However, using Differential Unitary Modulation technique in the multicarrier system become a big challenge because of the rising of the system complexity. In this paper, we introduce a low complexity differential modulation technique using the property of STBC. The proposed method is proven to provide high-quality performance with a low level of complexity.
