Abstract: An investigation of the signal detection scheme with Grover algorithm in MIMO-OFDM system is developed, and Grover algorithm is applied to find the minimum value in order to decide the sending sequence. In order to test the efficiency and reliability of this algorithm, the analysis and comparison between Grover algorithm, improved Grover algorithm and other traditional algorithms are made by Matlab simulation. Experimental results show that it can reduce the complexity, while achieving the same performance of the traditional optimum detection algorithms.
