Cyclic Prefix Optimization for OFDM Transmission over Fading Propagation with Bit-Rate and BER Constraints |
Abstract | ||
|---|---|---|
Orthogonal Frequency Division Multiplexing (OFDM) is a robust multi-carrier modulation technique for high data rata wired/wireless transmission systems due to its good performance in multi-path channels. In this paper, a chaos-evolutionary programming (CEP) hybrid approach is proposed to achieve a minimum degradation of OFDM transmission over multi-path channels, taking into account, the Doppler effect and Additive White Gaussian Noise (AWGN), under bit error rate (BER) constraint. CEP is employed to find the optimum length of the guard Interval (GI), which is proposed to overcome the problem of interferences that occur at the receiver. An illustrative example is given to verify the effectiveness of the proposed method. |
