摘要：
A novel channel estimation algorithm for sounding reference signal in DFT-Spread OFDM (DFT-S OFDM) system is proposed, which can estimate the channel response with high efficiency. According to the MSE metric between the estimated channel response and the real one, the simulation result shows that the intra-cell interference is neglectable while the effect of the inter-cell interference is so serious that certain IC (Interference Cancellation) techniques must be considered in the system design.
