Most of them are adopting CDMA to make it possible to use OFDM within the cellular network system, under the name "multicarrier CDMA." CDMA uses different spread spectrum codes for each user, thereby allowing multiple users to be handled on the same frequency band. This approach increases the number of users that can be handled within a single service cell of the mobile telephone network. Adding the concept of spread spectrum to OFDM, the multicarrier CDMA achieves the best combination of both approaches (Fig 2). This is rich. Do you actually read what you post, pest? If your posts are any indication, you are consumed with a hatred of QCDMA. Since you worship at the altar of OFDM and 802.111, it seems that your goal is to slam QCDMA. Why do you post something that shows CDMA being married to OFDM? Do you honestly think that Q has no IPR in such a combination? Some of the companies working on it are licensees. Do you honestly think Q has its thumb up its ass as respects OFDM? There are probably Q engineers working on 5G, 6G and 7G. You seem to have a very uninformed idea of how things work. But that's cool, you're probably young and all-knowing. Time will give you wisdom. Maybe not, some people are just plain deluded. Smart but deluded. Some of the smartest people I went to college with are complete failures in the real world. I knew they were smarter than I was. I suspect you might fall in that category. The grease from the MacDonald's grill where you flip must be toxic or delusion-inducing.
