Abstract :
The authors investigate the effect of adjacent carrier interference on the SNR under the overlapping carrier allocation scheme in FD/DS-CDMA. Filtering in transmitters and receivers is also considered. Analysis shows that interference caused by 20 other users in adjacent carriers is equivalent to the multiple access interference from one user within the desired carrier if the spectral spacing between adjacent carriers is 1.16 times the chip rate
