The unified approach for BER analysis of generic multi-code code division multiple access (CDMA) with optimized decision thresholds was discussed. It was concluded that the selective transmission multiple code CDMA (ST-scheme) is the general form of the single code CDMA (SC-scheme) and parallel transmission multi-code CDMA (PT-scheme) and the BER expression derived for the ST-scheme can be applied also to the others. The results showed that the choice of the H́ with respect to H in an ST-scheme should be carefully exercised to maximize the detection efficiency and bandwidth efficiency jointly.
