A study on multi-carrier DS-CDMA systems with multi-rate traffic

摘要

In this work, orthogonal multi-carrier direct sequence code division multiple access (DS-CDMA) system with multi-rate traffic is presented. Interference in such a system is severe because all users of all media transmit over the same assigned sub-carriers. We divide this interference into different types and analyze the system to obtain the bit error rate (HER) with random signature codes for an AWGN channel taking into account all interference types.
