Sparse expression and sensing of fast fading channel for OFDM systems with imperfect carrier synchronization
A sparse expression of fast fading channel and its sensing method were proposed for orthogonal frequency-division multiplexing (OFDM) system of sparse pilot under the condition of imperfect carrier synchronization.First,a sparsified core vector based sparse expression of the generalized channel impu...

| description | A sparse expression of fast fading channel and its sensing method were proposed for orthogonal frequency-division multiplexing (OFDM) system of sparse pilot under the condition of imperfect carrier synchronization.First,a sparsified core vector based sparse expression of the generalized channel impulse response (G-CIR) was proposed by deriving compressed sensing model of the sparse pilot system.Then,both the sparsified core vector and G-CIR were reconstructed by orthogonal matching pursuit(OMP).Simulation results demonstrate that the proposed algorithm can effectively reduce the bit error rate (BER) of the OFDM system with imper ect carrier synchronization. |
