Discrete-wavelet transform modulation over Multiple Input Multiple Output applications

Abstract

Discrete wavelet transform (DWT) for Multiple Input Multiple Outputs (MIMO) bandlimited systems is investigated. The implementation involves using the DWT as the base multiplexing technology at the baseband to process the input signal. Using the Alamouti diversity technique, an investigation for a DWT-MIMO multicarrier system is presented. Results shown are quite interesting; however these were very consistent with the earlier discussion presented in the original Alamouti work. The scheme is however implemented for DWT-MIMO case wherein more receiver diversity is of stern interest. Our implementation in favour to cover 2 xNr MIMO systems (Nr is the number of receiver's elements).
