greek carrier cdma
Generally speaking, the two major points of CDMA transceiver are as following,
1, pseudo-random code sequences, like M-sequences.
2, carrier modulation and demodulation, like PSK, QPSK etc.
Our problem is that we face a baseband transmission system, which does not contain carrier. Now, we need to implement Multiple Access. Of course TDMA can be used for that, however for some reasons; we do not plan to use this method.
Instead, we plan to “spread the spectrum” by only using the pseudo-random code sequences, without the carrier modulation.
Does it sound possible?
Could this method be also named CDMA?
Please give you advice. Thanks in advance.
