We generalized an constructing method of noncoherent unitary space time codes (N-USTC) over Rayleigh flat fading channels. A family of N-USTCs with T symbol peroids, M transmit and N receive antennas was constructed by the exponential mapping method based on the tangent subspace of the Grassmann manifold. This exponential mapping method can transform the(More)
This letter constructs a practical low- complexity coded modulation MIMO system which concatenates the IRA-LDPC codes based on the permutation Q-matrix with the noncoherent unitary space-time modulation (USTM) based on sine-cosine function for Rayleigh flat fading channel. In the receiver, we adopt dual detecting scheme: first relative coarse low complexity(More)
