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. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 31: 40–44, 2001.
