A Completely Blind Channel Estimation Technique for OFDM Using Generalized Constellation Splitting and Modified Phase-Directed Algorithm
Sameera Bharadwaja H., D. K. Mehra
The problem of blind channel estimation for SISO-OFDM systems using second-order statistics (SOS) is addressed. A comparison of two prominent SOS-based techniques: subspace-decompo…

A Completely Blind Channel Estimation Technique for OFDM Using Constellation Splitting
Sameera Bharadwaja H., D. K. Mehra
The problem of second-order statistics (SOS)-based blind channel estimation in OFDM systems is addressed in this paper. Almost all SOS-based methods proposed so far suffer from a c…
