Wavelet packet modulation for wireless communications
نویسندگان
چکیده
As proven by the success of OFDM, multicarrier modulation has been recognized as an efficient solution for wireless communications. Waveform bases other than sine functions could similarly be used for multicarrier systems in order to provide an alternative to OFDM. In this article, we study the performance of wavelet packet transform modulation (WPM) for transmission over wireless channels. This scheme is shown to be overall quite similar to OFDM, but with some interesting additional features and improved characteristics. A detailed analysis of the system’s implementation complexity as well as an evaluation of the influence of implementation-related impairments are also reported.
