Error performance of CE-OFDM based AF systems with relay selection
Constant envelope (CE) orthogonal frequency division multiplexing (OFDM) can develop the advantages of OFDM,and eliminate the shortcomings of high peak-to-average power ratio (PAPR) and sensitivity to non-linear distortion of power amplifiers.The error performance of OFDM based amplify-and-forward (...

| description | Constant envelope (CE) orthogonal frequency division multiplexing (OFDM) can develop the advantages of OFDM,and eliminate the shortcomings of high peak-to-average power ratio (PAPR) and sensitivity to non-linear distortion of power amplifiers.The error performance of OFDM based amplify-and-forward (AF) cooperative system with relay selection will be deteriorated due to feedback delay and other factors.Minimum mean square error (MMSE) Wiener channel predictor can alleviate the deterioration of error performance of wireless systems caused by feedback delay.For this reason,the CE-OFDM based AF cooperative system with relay selection and MMSE channel prediction which can overcome the shortcomings of OFDM and the influence of feedback delay was proposed,and its lower bound expressions for the average bit error rate (ABER) of rectangular quadrature amplitude modulation over Rayleigh block fading channels were derived.The numerical calculation and simulation results show that the lower bound expressions for the ABER of the above system has high accuracy when the modulation coefficients are small and can be used to design the AF cooperative system with CE-OFDM,channel prediction,and relay selection. |
