Abstract

Abstract

Single-Carrier Frequency-Domain Equalization (SC-FDE) and multi-carrier Orthogonal Frequency Division Multiplexing (OFDM) are two techniques to combat multipath fading in digital communications. This paper compares the BER performances of them for white Gaussian noise channel theoretically. By the value-changing property of Gaussian distributions tail probability, the following conclusion is drawn: OFDM is a little better than SC-FDE in BER performance for Sow Signal-to-Noise Ratio (SNR), while SC-FDE greatly outperforms OFDM for high SNR. This conclusion is significant to the design of the communication system for its important reference value.
