Matching signal dynamic range for turbo equalization system

摘要

A method for reducing a number of bits for representing a value is disclosed. A first value represented with a first number of bits is transformed to a second value represented with a second number of bits, wherein the first number of bits is greater than the second number of bits. The transformed second value is scaled by a scale factor to a third value. Transforming includes selecting a target window with a width of a third number of bits, wherein the third number of bits is smaller than the first number of bits. Transforming further includes saturating the first value to a most significant bit (MSB) within the selected target window and extracting bits within the selected target window from the saturated value.

1. A method for reducing a number of bits for representing a value, comprising:
transforming by a processor a first value represented with a first number of bits to a second value represented with a second number of bits, wherein the first number of bits is greater than the second number of bits, comprising:
selecting a target window with a width of a third number of bits, wherein the third number of bits is smaller than the first number of bits, and wherein the target window comprises a window of consecutive bits not including the least significant bit; and scaling by the processor the transformed second value by a scale factor to a third value.
