Abstract:
This research aimed to enhance Bluetooth Angle of Arrival (AoA) indoor positioning systems using Convolutional Neural Network (CNN) and channel coding, while analyzing the factors influencing its performance. A Bluetooth system with Low-Density Parity-Check (LDPC) codes is proposed as an alternative to the S2 and S8 coding schemes in the Bluetooth Low Energy (BLE) coded standard. The Viterbi algorithm is modified to obtain log-likelihood ratios (LLRs) from the correlation between reference signals and received signals. Additionally, a concatenated CNN model is proposed to improve indoor positioning accuracy. Simulations under Additive White Gaussian Noise (AWGN) channel conditions show that when the signal-to-noise ratio is greater than or equal to 3 dB, Bluetooth LDPC outperforms both standard BLE coded schemes. The average decoding time is approximately 17 times shorter, and the number of redundancy bits is about 7 times lower compared to BLE coded S8. Experimental results using a concatenated CNN also demonstrate superior performance, with a root mean square error of 2.434, compared to traditional methods. Furthermore, this approach offers greater flexibility compared to regression and classification models. The study suggests that the number of flipped bits during decoding provides insights into channel conditions, contributing to the enhanced accuracy of the concatenated CNN model. These two proposed methods can be used together to enhance communication reliability, thereby improving the accuracy of Bluetooth indoor positioning systems.
