ABSTRACT

Multicarrier (MC) systems are being proposed and tested for wireless data transmission in applications such as broadband wireless networking and digital broadcasting of audio and television. The combination of multicarrier modulation and code-division multiple access (CDMA) is seen as a very promising technique for the development of high-capacity wireless indoor communications. However, this scheme is very sensitive to multi-user interference.
In this work, we consider the classical MC-CDMA architecture modified by the introduction of sequence chip modulation on each subcarrier. The introduced orthogonal sequences, with suitable arrangement for each user, will show multi-user interference cancellation and increase the bandwidth required for each sub-carrier, enhancing by that the system performance. The results are given in terms of bit error rate (BER) obtained by an analytical approach for additive white Gaussian noise (AWGN) in Rayleigh fading channel.
