Strategic Study of CAE 2007, Volume 9, Issue 12,   Pages 81-85

Abstract: endtoend data transmission scheme based on OFDM mechanism with good robustness against the RPE-LTP vocoderAccording to the character of RPE-LTP vocoder, data are modulated to orthogonal lowfrequency sinusoidaldone by IFFT and the modulated signals are conformed to the time and frequency characters of RPELTP vocoder
