Wavelet packet transform in MIMO - OFDM systems

Wavelet Packet Transform (WPT) can be used in Orthogonal Frequency Division Multiplexing (OFDM) systems to overcome some disadvantages of this system. Besides, OFDM technique combined with Multiple-Input-Multiple-Output (MIMO) technique to form the MIMO - OFDM systems that have more advantages such as high data rate or high performance. According to the advantages of WPT and MIMO - OFDM systems, there is an idea to use WPT in MIMO - OFDM systems to make use of all advantages of MIMO - OFDM and WPT.
