Research and simulation of OFDM-CDMA base band signal processing system
Lili Guo · Applied science and technology · 2005
OFDM is a scheme for serial data stream to be transmitted by a parallel form, which can achieve highly effective use of frequency spectrum. Meanwhile, it has advantages in resistance of narrow band noise, reduction of the speed of sub-channel codes and elimination of ISI kinds. CDMA has strong ability in multi-addres saccess. OFDM-CDMA combines the superiorities of these two, making it become the key technique for 4G. So, from the angle of application,it is of great infortance to expatiate the wooking principle and the system architecture of the base band signal process platform, and put forward a design scheme with main parameters.
