Abstract :
Multicarrier technology can be integrated into LAS-CDMA system. Based on the non-orthogonal multicarrier LAS-CDMA system, the orthogonal LAS-CDMA system is introduced in this paper. As different subcarriers get the diversity gain but not the multiplexing gain, the performance is good enough for high bit rate transmission. By suitably designing the spread spectrum codes, we can eliminate the intersymbol interference and multiple access interference because of the good correlation property of LAS codes. So that it is very useful in wireless or mobile communications.
