Abstract
A hybrid pulse interval-modulation code division multiple access (PIM-CDMA) is proposed. An expression for the bit-error rate(BER) is given. Numerical results presented are compared with hybrid PPM-CDMA and OOK-CDMA schemes. For a low number of users, PIM-CDMA achieves similar and marginally lower BER performance compared with PPM�CDMA and OOK-CDMA, respectively. For a large number of users, it offers better performance compared with OOK.
