| Summary |
In this paper, we propose a spread sequence for asynchronous multicarrier code division multiple access (MC-CDMA). In MC-CDMA systems, performance degradation is mainly caused by nonlinear distortion due to high power amplifier (HPA) and multi-user interference. Since the peak envelope power (PEP) of multicarrier signals show large value, it is desirable to reduce the PEP as well as the multiuser interference components. The sequence, we propose, is based on the Hadamard and complementary sequence. Both of sequences are generated by similar procedures. To evaluate the performance of MC-CDMA system applying proposed sequence, we simulate the system under the effect of nonlinear amplifier. |
