| titleOfInvention | Transmission method for non-codebook based precoding in rapidly time-varying mimo system |
| abstract | The present invention provides a transmission method for a non-codebook based precoding in a rapidly time-varying MIMO system. The method is characterized in that: for a receiving terminal, S1: receiving signal ŷ and a pilot frequency transmitted by a transmitting terminal and processed for simultaneous precoding, on the basis of the pilot frequency, completing a channel estimation, and acquiring an equivalent channel H t,equ ; S2: performing an order-based QL decomposition on the equivalent channel H t,equ , and acquiring a set of permutation matrix P μ , a unitary matrix Q, and a lower triangular matrix L having ordered elements on the diagonal; S3: performing a process of y = Q H ŷ on signal ŷ on the basis of the unitary matrix Q; S4: on the basis of the lower triangular matrix L, performing a serial interference cancellation on the processed reception signal y = Q H ŷ, thus acquiring signal ^x p ; S5: on the basis of the permutation matrix P μ , performing a permutation operation on signal ^x p , thus acquiring signal ^x; S6: completing a demodulation and decoding of signal ^x. The lower triangular matrix L, acquired on the basis of the technical solution of the present invention, allows for an improved descending feature to be maintained in a high speed movement environment. The performance of the serial interference cancellation technology is ensured, and the interference among sub-channels in the rapidly time-varying MIMO system is reduced. |
