摘要：

In wireless communication systems data recovery represents an important challenge at receiver's end. The performances of MC-CDMA systems can be improved by using OFDM technique. This paper illustrates the improvement brought in MC-CDMA OFDM systems when choosing the LDPC coding/decoding technique and the appropriate spreading sequences to separate the users. There have been tested the performances of the system in BER vs SNR terms when Walsh, Kasami and PN spreading sequences are used for the MC-CDMA OFDM system. The final goal is to obtain the best combination between LDPC technique and spreading codes in order for the performances to be increased.
