Abstract :
A family of the generalized quadrature modulation (GQM) structures is proposed that includes a prototype FIR or IIR filter within the structure. By choosing a proper filter and setting a single parameter many applications can be exploited, such as tunable band-pass filtering, band-pass Hubert transformation, single-sideband processing, band-inversion processing, etc. In other words, the GQM structures generalize the existing quadrature modulation systems and also have the potential to exploit other applications.
