摘要
The system framework and imaginary interference were analyzed aiming at the problem of symbol detection and channel estimation in order to effectively improve the communication quality of filter bank multicarrier (FBMC) system. A channel estimation and detection method for FBMC system was proposed based on deep learning. A complete simulation system was established by combining FBMC-offset quadrature amplitude modulation (OQAM) with deep learning model, and the characteristics and label processing of received data were designed. ResNet-DNN neural network was used to model the channel symbol detection module. The original model structure and optimized model parameters were improved, which improved the accuracy of symbol detection compared with traditional classifiers. CNN+NN model was used to model and integrate for estimating, equalizing and detecting channel symbols. The theoretical analysis and simulation results show that the new method is superior to orthogonal frequency division multiplexing (OFDM) system and FBMC system based on pilot estimation in terms of noise resistance, robustness and bit error rate (BER) performance. © 2020, Zhejiang University Press.
