An Evaluation of Coded Wavelet for Multicarrier Modulation with OFDM

, 2013
Orthogonal frequency division multiplexing (OFDM) is pronounced in wireless communication systems. Methods for improving the performance of the OFDM-based systems are mostly sought. A method of doing this involves error correction coding and another, a better multicarrier modulation kernel.
