CORRELATION COMPUTATION CIRCUIT AND METHOD FOR INTERFERENCE NOISE SEQUENCE MATRIX

摘要

Embodiments of the present invention disclose a correlation computation circuit and method for an interference noise sequence matrix, which relate to interference noise sequence matrix correlation computation, and efficiency of the whole interference noise sequence matrix correlation computation can be improved. The circuit includes: a noise item computation unit, used for performing noise item computation according to antenna data; a register, used for storing noise item computation results computed by the noise item computation unit; a first delay logic circuit, used for controlling the register to send the noise item computation results computed by the noise item computation unit to a matrix computation unit prior to all noise items computation being computed by the noise item computation unit; and a matrix computation unit, used for computing correlation results of the interference noise sequence matrix with the noise item computation results. They are mainly applied to the correlation computation of the interference noise sequence matrix.
