Channel Estimation for OFDM Systems: Techniques, Algorithms, and Performance
The use of OFDM is gaining more and more interest from communications and signal processing communities due to its great potential to cope with frequency-selective channels. Further, OFDM also allows to reduce the complexity for tasks such as equalization and channel estimation in systems where the bandwidth of the channel is wide, when compared to classical (non-OFDM) approaches.
