SC-FDE and OFDM in MISO Frequency-Selective Fading Channels
This paper presents a new approach for evaluating the differences between SC-FDE and OFDM in MISO Clarke/Gans Rayleigh fading channel. At first, base-band models of SC and OFDM are elaborated and principles of STBC encoding and decoding are described in the MISO fading channel. The Clark/Gans Rayleigh fading channel is then defined and extended to create MISO multi-path frequency-selective channel. BER performances are simulated in MATLAB for different level crossing rates and both systems are compared in terms of PMEPR.
