An apparatus is configured to perform a method that includes dividing a complex number into a real portion and an imaginary portion. The method also includes determining a region among a plurality of regions in a matrix based on a magnitude of the real portion and a magnitude of the imaginary portion, wherein each region of the plurality of regions includes three sub-regions. The method further includes determining a sub-region among the three sub-regions of the determined region based on the magnitude of the real portion and the magnitude of the imaginary portion. In addition, the method includes coding the real portion and the imaginary portion of the complex number using a common exponent, wherein the common exponent depends on the determined region and the coding depends on the determined sub-region. The method further includes storing the coded complex number in a memory that is accessible for communication signal processing. |
