Can the AD9957 Evalboard and software generate CDMA modulation of the AD99957?

 

In general, the AD9957 can produce any modulated signal that relies on a
complex baseband component (I + jQ). The AD9957 evaluation software only
supports the generation of a limited set of complex baseband formats such as
QAM, GMSK, etc.


In most cases, one would drive the AD9957 data port with an FPGA containing the
necessary hardware to generate the desired digital complex baseband signal. As
long as CDMA satisfies the condition of being a complex baseband signal, then
the AD9957 will be able to produce a CDMA output signal.
