Wavelet Modulation and Transmission Through Fading Channels
Abstract
In separate parts, this report addresses: (1) the use of multiscale modulation to obtain bandwidth-efficient modulation, and the performance of such modulation in fading channels; and (2) the analysis of transmission through fading channels, and approaches to the design of transmitter and receiver waveforms which will perform optimally in fading channels. In the first case, it is shown that using wavelet and/or scaling waveforms can lead to modulation which is comparable to, or better than, many conventional schemes, including GMSK. Performance in fading channels is similar to that of other methods. In the second part, the performance of multiscale signaling is addressed using the matched-filter band method. The signal design problem is formulated as an optimization problem and an analysis approach outlined which leads to maximization of SNR in fading channels.
