Abstract This paper presents a decoupled maximum likelihood(ML) detection algorithm, which utilizes the orthogonal characteristic of signal, decoupled the combined ML detection into separated one, under the assumption that CSI is known at the receiver. Utilizing appropriate channel estimation algorithm, the decoupled algorithm not only sharply reduces the computational complexity compared to the noncoherent ML detection, but also improves the performance. Simulation results confirm the effectiveness of the algorithm.
