QPSK modulator/demodulator

hi,
well first of all i'm student in university of kent at canterbury ,and i'm
trying to build QPSK modulator and demodulator using ALTERA MAXII, and i'm
trying to build all my transivers to be in one chip , and i stuck in one
piont ,how to generate sine and cosine wave using direct digital
synthesizer(DDS),how to build this design in ALTERA and what is the best
components to be used ,and i have to mention that my carrier frequency is
constant ,and i don't need to change it ,
or is there any way to use good integrated circuit could genrate digitally
sine wave , and what is it pzz?...
could u halp me in that and i will be greatfull .
best wishes .

Re: QPSK modulator/demodulator

please provide me with some information about
the hardware structure of qpsk modulator
,the quadrature oscillator made of LM747C ic and about the hardware that should be employed in the linear adder at the modulator end(qpsk).
the oscilltor frequency is 20 khz and the information signal frequency is from 1 khz to 3khz, with best regards......
