Bit error rate (BER) of multiuser detection (MUD) receivers can be measured by the cross correlation matrix whose elements are correlation values of users signature waveforms. We investigate the cross correlation matrix for chip-asynchronous DS/CDMA system. Simultaneous optimization of spreading codes and chip waveforms is discussed which leads to a lower bound of mean squared multiple access interference (MAI). |
