Hi,

I am implementing Quadrature Amplitude modulator in verilog.
In this first the serial data is converted into parallel form
and applied directly to the pulse shaping filter(interpolation by factor 4).
But my doubt is, how we can apply parallel bits(0's and 1's)directly to the
filter??????
In my reference paper the input to filter is marked as 2-bit parellel data and
output is marked as m-bit parellel data...

Can anybody help me please........
