Convolutional Neural Networks for Space-Time Block Coding Recognition

10/19/2019 ∙ by Wenjun Yan, et al. ∙ 0

We find that the latest advances in machine learning with deep neural network by applying them to the task of radio modulation recognition, channel coding recognition, and spectrum monitor. This paper first proposes a novel identification algorithm for Space-Time Block coding(STBC) signal. The feature between Spatial Multiplexing (SM) and Alamouti (AL) signals is extracted via adapting convolutional neural networks after preprocessing the received sequence. Unlike other algorithms, this method does not require any prior information of channel coefficient, and noise power and, consequently, is well-suited for non-cooperative context. Results show that the proposed algorithm performs well even at a low signal to noise ratio (SNR).
