| Abstract: | Compressed sensing is a new theory of collection and processing data,in which a sparse signal can be reconstructed successfully from far fewer data/measurements.The quality of Channel estimation which is seemed as one of the OFDM key techniques impacts on overall system performance directly.In this paper,we consider channel estimation using the compressed sensing for the sparse channels such as ultra-wideband channel and underwater acoustic channel in OFDM systems.This work leads to a common describe of spa... |
