  • Method for moving quantization noise introduced in fixed-point calculation of fast fourier transforms
    Patent number: 8483202
    Abstract: The invention discloses a method in an electronic communication device for processing a digital signal within a wireless communication network in order to transform the digital signal from a first domain representation to a second domain representation in a communication device, comprising the steps of: transforming the signal from the first domain to the second domain resulting in a signal of a first order of values with quantization noise in at least one area of the second domain, and performing a cyclic shift on the transformed signal to move the quantization noise in the second domain, resulting in a first shifted signal.
