| Abstract: | Recently,compressive sensing(CS) technology is a hot research topic in signal processing area,this technology could sample the sparse signal at a rate much lower than Nyquist rate and reconstruct it with high probability by optimization technique.CS-based channel estimation could reduce the number of pilot symbols and has a better estimation performance as compared with traditional channel estimation.Two different CS-based channel estimations in orthogonal frequency division multiplex(OFDM) system and ultra... |
