Article Preview

An improved FPGA implementation of channel estimation based on pilot arrangement is proposed in this paper. Typical methods are firstly investigated and compared by MATLAB simulation. The paper puts the pilots to the least square criterion to estimate the channel frequency domain response by using linear interpolation method with comb-type pilots arrangement in FPGA implement, it makes a good balance between algorithmic capability and FPGA design complexity. The simulations prove that the design can accomplish channel estimation and emendation, and it can meet the demand of the system.
