Abstract :
This paper presents a new multi-carrier DS-CDMA system with multi-code in which input data bits are first coded at a low rate (I/R) and resulting R coded binary bits are then multiplexed with a set of multi-codes to produce code division multiplexing (CDM) super-bits. After serial-to-parallel conversion, they are spread-spectrum transmitted using M orthogonal carriers. Based on a conventional matched-filter and RAKE receiver for each carrier, the performance is analyzed partially and simulated. The numerical results show that the proposed scheme has close bit error rate (BER) performance, but better anti-jamming ability compared to the normal multi-carrier DS-CDMA system
