Blind channel identification for OFDM-based SIMO systems
MetadataShow full item record
We introduce blind channel identification and equalization for orthogonal frequency division multiplexing (OFDM) system using a guard interval (GI). To perform channel identification, Subspace-based methods are proposed. To achieve enhanced performance and robustness to channel frequency nulls, receiver diversity and OFDM is combined. The performance of the proposed system is illustrated by computer simulations. ©2008 IEEE.
