Abstract:
1. An apparatus comprising: a plurality of filter elements, wherein each filter element of said plurality of filter elements has an individual filter transfer function; a multiplier configured to multiply a frequency domain base band signal by an inverse filter transfer function of said plurality of filter elements, wherein multiplying said frequency domain base band signal by said inverse filter transfer function of said plurality of filter elements includes multiplying said frequency domain base band signal by a coefficient vector that includes inverse filter transfer functions of said plurality of filter elements, and wherein said coefficient vector includes both real and complex numbers; and a frequency-to-time domain converter configured to convert an output of said multiplier from a frequency domain signal to a time domain signal and provide said time domain signal to at least one of said plurality of filter elements; wherein said plurality of filter elements are configured to filter said time domain signal.
