Performance of constant envelope OFDM system with nonlinear power amplifier by Qingbo WANG

“…Orthogonal frequency division multiplexing technology is widely used in wireless communication system due to its high spectral efficiency and good resistance ability to frequency selective fading.But it has high peak-to-average power ratio.Therefore,OFDM system needs large input power back-off to avoid signal distortion when using nonlinear power amplifier.In order to study the performance of the system under the condition of nonlinear power amplifier,the implementation of constant envelope OFDM was analyzed.Taking bit error rate as an index,the performance comparison between CE-OFDM system and OFDM system using traditional iterative limiting filter PAPR suppression technology were given under additive white Gaussian noise channel and multipath fading channel.…”

Design of SCMA codebook based on chaotic signal and system performance analysis by Geng ZHAO, Yanyan MA, Yingjie MA

“…Sparse code multiple access (SCMA) technology is one of the multiple access technology schemes for the new generation of 5G.In order to solve the transmission requirement of massive users,the logistic chaos sequence was proposed instead of the random sequence in the original system to select the codeword.The constellation method based on trellis coded modulation (TCM) subset segmentation with the mapping matrix was used to generate codebook in the encoder,and decoded through message passing algorithm (MPA) detection method.The simulation results show that the bit error rate (BER) is low when the system uses the pseudo-random sequence of chaos to select the codeword,and the system also performs well under the condition of high overload rate.…”

“…Based on the characteristics of quality scalable video coding,a fast inter encoding algorithm was proposed on the enhancement layer for the medium-grain quality scalability（MGS）.Firstly,based on the base layer macroblock mode and rate-distortion,the order of the coding mode for the current macro block was proposed.Then based on the encode structure,the correlation between layers,and the spatial correlation,desicions for the Direct coding mode,layer mode,and adjacent mode were proposed,respectively.Finally,the macroblocks were encoded in the order predicted,with the proposed three decisions to improve on the coding speed by early termination.The experimental results show that the computational complexity of the algorithm is reduced by 68% on the average compared to that of the standard method,with only negligible coding loss and bit-rate increase.…”
