ABSTRACT
The multicarrier (MC) transmission technique was devised in the 1960`s for voice band data transmission. Today there are two principle MC applications, one is for the high speed digital subscriber loop and the other is for the broadcasting of digital audio and video signals. In this work the use of multi carriers for high-bit rate wireless applications are considered. The bit error rate (BER) performance of multi carriers with quadrature amplitude modulation (QAM) and offset quadrature amplitude modulation (OQAM) with guard interval in a fading environment is considered via the use of Monte Carlo simulation methods. BER results are presented for OQAM using guard interval to immunity the multi path delay for frequency Rayleigh fading channels and for two-path fading channels in the presence of additive white Gaussian noise (AWGN). The BER results are presented for Multi carrier offset 16 Quadrature Amplitude Modulation (MC/offset 16 QAM) and MC with offset differentially Encoded 16 Quadrature Amplitude Modulation (MC/offset 16 QAM) for frequency flat Rician channel in the presence of additive white Gaussian noise (AWGN). The performance of multicarrier system is also compared with equivalent single carrier systems.
