Transceiver Design and Performance Analysis of Space Time Coded Fractal Modulation

The filterbank transceiver structure for fractal modulation has been developed. It has been shown that the transceiver complexity is comparable to that of OFDM.The use of orthogonal space time block codes (OSTBC) in conjunction with Fractal Modulation (STFrM) in the presence of frequency selective fading channels has also been considered. An L scale fractal modulation and coherent demodulation effectively converts a frequency selective channel into L flat fading channels per information symbol with random scale gains. The analysis of the proposed scheme in terms of bit error rate has been performed. A diversity order of mTmRL can be achieved, where mT,mR are the number of transmitters and receivers, respectively. This increase in diversity order in comparison with that achieved for the OFDM case is at a cost of lower spectral efficiency. However the spectral efficiency of STFrM can be improved R times by the use of multiplicity ‘R’ multiwavelets.
