Each communication system requires channel equalization to compensate systematic distortions resulting from propagation effects like multipath spread or Doppler shift. A major advantage of Orthogonal Frequency Division Multiplexing (OFDM) is the simplicity of channel equalization in frequency domain. The channel state information for adequate equalization can be gained by transmitting known signals, called pilot tones. The way of distributing those pilots among payload tones and the way of interpolating them is decisive for the equalization quality and must be matched to the channel characteristic. This study compares different pilot distributions and interpola- tion techniques and gives details of a runtime-flexible implementation on a self-desig- ned FPGA-based Software Defined Radio (SDR) platform.
