    Abstract: Embodiments herein achieve a method and system for selecting non-coherent spreading sequences with binary alphabets {0, 1} with variable spreading factors. The method generates circular shift equivalent sets of spreading sequences by circularly shifting base sequences with elements {1, 0} and having at least one variable spreading factor. The method determines whether each spreading sequence in the circular shift equivalent set meets pre-defined spreading sequence criteria. The spreading sequence criteria comprise balanced criteria, a non-repetition criteria, non-circular criteria, and conjugate criteria. Furthermore, the method selects the spreading sequence from expansions of at least one spreading sequence from the circular shift equivalent sets in response to determining that the spreading sequences in the circular shift equivalent sets meets the pre-defined spreading sequence criteria.

    Abstract: A sliding intermediate frequency (IF) receiver and a sliding IF reception method are provided. A first local oscillation signal and a second local oscillation signal may be generated, based on a division ratio of a frequency of the first local oscillation signal to a frequency of the second local oscillation signal that is determined in advance so that an amount of power to be consumed or an error rate of the sliding IF receiver is optimized. A received input signal may be converted to a first IF signal, based on the first local oscillation signal, and the first IF signal may be converted to a second IF signal, based on the second local oscillation signal.
