WebJul 18, 2024 · Abstract: This paper considers the transceiver design for uplink massive multiple-input multiple-output (MIMO) systems with channel sparsity in the angular domain. Recent progress has shown that sparsity-learning-based blind signal detection is able to retrieve the channel and data by using massage-passing-based sparse matrix … WebBlind channel estimation techniques are proposed to re-duce the pilot overhead for channel acquisition. In [13], the authors exploit massive MIMO channel sparsity in the angular domain to blindly estimate the channels. However, the proposed technique in [13] is an iterative solution, and singular value decomposition of the covariance matrix of the
