摘要
A hybrid pulse interval modulation-code division multiple access (PIM-CDMA) is proposed. Air 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. (C) 2001 John Wiley & Sons, Inc.
