| The application of frequency domain equalization techniques makes single carrier modulation a potentially valuable alternative to OFDM, especially in regard to its lower peak-to-average transmit power ratio and less sensitivity to carrier frequency offset. In this paper, we bring up a novel single carrier frequency domain equalizer (SC-FDE), this new SC-FDE needs not a cyclic prefix (CP. The cyclic prefix not only wastes transmits power, but also degrades transmission efficiency. As cyclic prefix is not required, we can reduce the system complexity greatly. We will simulate the conventional scheme and the new scheme over Rayleigh fading channel, performance and complexity comparisons are presented between the traditional scheme and the proposed scheme. |
