Deep Learning-Based CSI Estimation for Massive MIMO: CNN-LSTM vs Traditional LS and MMSE Techniques
Objective
The objective is to develop a hybrid CNN-LSTM model for precise CSI estimation in mMIMO systems, evaluate its performance against conventional LS and MMSE estimators, and demonstrate its effectiveness in reducing NMSE, improving signal power, and lowering BER.
Abstract
Channel state information (CSI) estimation is a critical challenge in massive multiple-input multiple-output (mMIMO) systems, directly influencing beamforming and signal detection performance. This study explores a deep learning-based approach utilizing a hybrid Convolutional Neural Network (CNN) and Long Short-Term Memory (LSTM) network for CSI estimation. The proposed model is trained on synthetic channel datasets and compared with conventional Least Squares (LS) and Minimum Mean Square Error (MMSE) estimators. Simulation results demonstrate that the CNN-LSTM model significantly reduces the normalized mean square error (NMSE), improves received signal power, and lowers bit error rate (BER) across varying signal-to-noise ratio (SNR) levels. These findings highlight the potential of deep learning techniques in enhancing CSI estimation accuracy for next-generation wireless communication systems.
