Multi Binary Turbo Coded WOFDM Performance in Flat Rayleigh Fading Channels
Journal Title: Acta Technica Napocensis- Electronica-Telecomunicatii (Electronics and Telecommunications) - Year 2008, Vol 49, Issue 3
Abstract
In this paper, the application of Multi Binary Turbo Codes (MBTCs) to two multicarrier modulation techniques used for transmission in the flat radio fading channel is studied. Thus, the performance of the coded versions of Orthogonal Frequency Division Multiplexing (OFDM) and of its wavelets based version (WOFDM) is evaluated under several simulation scenarios. These scenarios take into account the time variability of the radio channel, by the mean of the Doppler shift parameter. An important conclusion is that, under the assumptions made in this paper, WOFDM outperforms OFDM. By the other hand, this technique shows little influence on the choice of the wavelets mother used in the modulator.
