Hi all ,
I am new to DSP and am trying to get my fundamentals clear about
quadrature processing. I am looking at working and preexistent BPSK
mod/demod code which uses cos(theta) to encode 1 and -cos(theta) to
encode 0. After down conversion the code looks at only the imaginary
part of of the data to decode a 0 or 1. I understand the the real part
is always zero.
But I dont the science. I have read books about Qadrature processign
but non has cleared all the gray areas.
I am hoping I can get some help from gurus at comp.dsp.
