Channel transfer function matrix processing device and processing method therefor in V-BLAST

摘要

The present invention can be employed in the V-BLAST receiver of the MIMO communication system and provides a channel transfer function matrix and a processing method of the channel transfer function processing unit which can process the channel transfer function matrix more efficient. ; According to the invention, converting a channel transfer function matrix (H) by using a predetermined log log conversion table, and calculates a Hermitian matrix of the log-converted channel transfer function matrix (H) (H ^H). Next, to calculate the product matrix (A) by using the addition and operation of the log-transformed Jockey Jacobian matrix channel transfer function and the Hermitian matrix and calculating the determinant of a woman character, and the inverse matrix (A ^-1) of the matrix are multiplied, . After two chairs and a woman using a Jacobian determinant Jockey addition and operations of each of the above Hermitian matrix ^(H H) calculating a pseudo inverse matrix, the pseudo-inverse calculation using an inverse logarithmic conversion table to convert the station log. ; V-BLAST decoder according to the present invention without carrying out the real domain operation that requires a large amount of a multiplier, an input channel transfer function matrix (H) by taking the binary log and to convert it to a value in the log domain, a simple adder and It can be implemented by using the Jacobian jockey. ; V-BLAST, the channel transfer function, the pseudo inverse matrix, Jockey Jacobian, log domain
