Claim One:
1. A method of modulating a carrier for transmitting a quadrature vestigial single sideband (QVSB) signal for communicating I symbols and Q symbols, the method comprising the steps of, cross arm filtering the I and Q symbols for generating i filter responses and i H filter responses from the I symbols and for generating q H filter responses and q filter responses from the Q symbols, combining the i and q H filter responses into an I channel overlapping filter signal and the q and i H filter responses into a Q channel overlapping filter signal, and quadrature modulating a carrier by the I and Q channel overlapping filter responses into a modulated inphase signal and a modulated quadrature signal, the Q channel overlapping filter response modulates the carrier shifted ninety degrees from the carrier modulating the I channel overlapping filter responses for modulating the carrier in quadrature, summing the modulated inphase signal and a modulated quadrature signal into the QVSB signal, and transmitting the QVSB signal for communicating the I and Q symbols over a single sideband.
