A Blind Channel Estimation Method for OFDM: Subspace-Based Approach
A blind channel estimation technique for OFDM systems - subspace-based blind channel estimation method with implementation insights
Estimation of Signal Parameters via Rotational Invariance Techniques (ESPRIT) Algorithm
The ESPRIT algorithm is one of two classical subspace estimation methods that effectively estimate signal eigen-subspaces, featuring implementations of both LS and TLS estimation approaches with code-level descriptions of key functions.
