Abstract(in English) | A new modulation method using orthogonal wavelets is proposed as a multi-carrier modulation method. In discrete wavelet decomposition the size of the time-frequency window is fixed and therefore a phased series which has a different length for the time axis is obtained. We apply transmission signals to this decomposed series and the composed wavelet waves are used for transmission. Multi-rate, multi-performance transmission is thus realized. This may also be regarded as an unequal error protection (UEP) code. In this paper the algorithm of this method is shown, and the bit error rate (BER) performance with 16QAM (quadrature amplitude modulation) as the signal constellation is evaluated through computer simulations. |
