Re: [Discuss-gnuradio] CDMA in GNURadio

[Brook Lin]

Hi  Brian and All,

Thanks for your last reply about implementing CDMA in GNURadio. I read some
materials on synchronization and also the OFDM examples in GNURadio. Is that
possible if I add a Code block into the OFDM block diagram to implement
MC-CDMA?

For the OFDM Transmit path:
frame source -> symbol modulation -> insert preambles -> IFFT -> add cyclic
prefix -> scale -> USRP

Can I add a code block into this path to get MC-CDMA, like
frame source -> symbol modulation -> code -> insert preambles -> IFFT -> add
cyclic prefix -> scale -> USRP

Is this possible for implementing the MC-CDMA. Can I apply the same
synchronization method for OFDM into MC-CMDA? Please advise me.

Thanks,
Brook
