This paper introduces a new differential spatial modulation (DSM) scheme which subsumes both the previously introduced DSM and high-rate spatial modulation (HR-SM) for wireless multiple input multiple output (MIMO) transmission. By combining the codeword design method of the HR-SM scheme with the encoding method of the DSM scheme, we develop a high-rate differential spatial modulation (HR-DSM) scheme...
This paper proposes a high-rate spatial modulation transmission scheme based on the concept of Spatial Constellation (SC) and SC codewords introduced in [1]. In the proposed scheme, transmitted signal vectors are generated by multiplying spatial SC codewords with constellation symbols drawn from a conventional QAM or PSK constellation. The entries of SC codewords will determine how the constellation...
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...
