Wavelet Packet Transform Modulation for Multiple Input Multiple Output Applications

No / An investigation into the wavelet packet transform (WPT)
modulation scheme for Multiple Input Multiple Output
(MIMO) band-limited systems is presented. The
implementation involves using the WPT as the base
multiplexing technology at baseband, instead of the traditional
Fast Fourier Transform (FFT) common in Orthogonal
Frequency Division Multiplexing (OFDM) systems. An
investigation for a WPT-MIMO multicarrier system, using the
Alamouti diversity technique, is presented. Results are
consistent with those in the original Alamouti work. The
scheme is then implemented for WPT-MIMO and FFTMIMO
cases with extended receiver diversity, namely 2 ×Nr
MIMO systems, where Nr is the number of receiver elements.
It is found that the diversity gain decreases with increasing
receiver diversity and that WPT-MIMO systems can be more advantageous than FFT-based MIMO-OFDM systems.
