Multirate MC-DS-CDMA transmitter for 4G communications

The scheme of a multirate 4G transmitter based on MC-DS-CDMA is proposed. The system is designed to minimize intercarrier interference (ICI) and multiaccess interference (MAI), taking into account the autocorrelation properties of the CDMA codes assigned to each user on each subcarrier. The system e...

Zusammenfassung:	The scheme of a multirate 4G transmitter based on MC-DS-CDMA is proposed. The system is designed to minimize intercarrier interference (ICI) and multiaccess interference (MAI), taking into account the autocorrelation properties of the CDMA codes assigned to each user on each subcarrier. The system employs two layered spreading codes in a similar way to UMTS, so it will be simple to design terminals that support both systems. The proposed scheme can be employed in both synchronous or asynchronous uplink and downlink. The transmitter is very versatile and it provides multiple possibilities to allow multirate users.
