Abstract:
A method for reducing a sampling rate of a signal for use in a communications receiver, comprising:a) receiving an in-phase component and a quadrature phase component of a signal;b) sampling said in-phase component and said quadrature phase component of said signal to create a sampled in-phase component and a quadrature phase component of said signal;c) delaying said sampled in-phase component and said quadrature phase component of said signal to create a delayed in-phase component and a delayed quadrature phase component of said signal; andd) downsampling said sampled in-phase and quadrature phase components and said delayed in-phase and quadrature phase components of said signal to create a downsampled in-phase component, a downsampled quadrature phase component, a downsampled delayed in-phase component, and a downsampled delayed quadrature phase component.
