Autor: Onebunne D. K., Nwabueze C. A., Ekengwu B. O., Odukwe P. C.

Publikováno v: International Journal of Advanced Networking and Applications. 14:5378-5384

This paper has developed a discrete wavelet transform (DWT) for multicarrier modulation in MIMO-OFDM system. The proposed system used additive Gaussian white noise (AGWN) and Rayleigh flat fading channel with respect to SNR using binary phase shift k

Autor: Odukwe P. C, Mbachu C. B., Ekengwu B. O., Onebunne D. K.

Publikováno v: International Journal of Advanced Networking and Applications. 14:5361-5366

This paper proposed precoding of OFDM signal using Discrete Cosine Transform (DCT) and adding of Log companding algorithm so as to reduce PAPR. Three scenarios were considered to fully examine the effect of PAPR in OFDM system based on simulations co
